James I of Scotland

James I (late July 1394 – 21 February 1437) was King of Scots from 1406 until his assassination in 1437. The youngest of three sons, he was born in Dunfermline Abbey to King Robert III and Annabella Drummond. His older brother David, Duke of Rothesay, died under suspicious circumstances during detention by their uncle, Robert, Duke of Albany. James's other brother, Robert, died young. Fears surrounding James's safety grew through the winter of 1405–1406 and plans were made to send him to France. In February 1406, James was forced to take refuge in the castle of the Bass Rock in the Firth of Forth after his escort was attacked by supporters of Archibald, 4th Earl of Douglas. He remained at the castle until mid-March when he boarded a vessel bound for France. On 22 March, an English vessel captured the ship and delivered the prince to Henry IV of England. The ailing Robert III died on 4 April and the 11-year-old James, now the uncrowned King of Scots, would not regain his freedom for another eighteen years.

James was educated well during his imprisonment in England, where he was often kept in the Tower of London, Windsor Castle, and other English castles. He seems to have been generally well treated, and he developed a respect for English methods of governance. James joined Henry V of England in his military campaigns in France between 1420 and 1421. His cousin, Murdoch Stewart, Albany's son, who had been an English prisoner since 1402, was traded for Henry Percy, 2nd Earl of Northumberland, in 1416. However, Albany refused to negotiate for James's release. James married Joan Beaufort, daughter of the Earl of Somerset, in February 1424. This was just before his release in April. The king's take back into Scottish affairs was not altogether popular, since he had fought on behalf of Henry V in France and at times against Scottish forces. Noble families now faced increased taxes to cover the ransom payments, and would also have to provide family hostages as security. James, who excelled in sports such as wrestling and tennis, literature, and music, also strongly desired to impose law and order on his subjects. Sometimes he applied such order selectively.

To secure his position in the Scottish court, James launched pre-emptive attacks on some of his nobles beginning in 1425 with his close kinsmen, the Albany Stewarts. This resulted in the execution of Duke Murdoch and his sons. In 1427 James called all the Highland clans to a parliament in Inverness. They came in great numbers. There, James treacherously murdered some and imprisoned others, effectively destroying any peace he might have had with them. He was said to be amused at the success of his plot. One of those imprisoned at Inverness was Alexander, Lord of the Isles, along with his mother, Mariota, Countess of Ross, who James kept prisoner on the island of Inchcolm in the Firth of Forth. Because of his betrayal, James was never again trusted by those in the Isles and the North.

Archibald, 5th Earl of Douglas, was arrested in 1431, followed by George, Earl of March, in 1434. The fate of Scottish prisoners in England was ignored by Scotland's ruling elite and the repayment money was diverted into the construction of Linlithgow Palace and other schemes. In August 1436, James's siege of Roxburgh Castle failed, and he subsequently faced an ineffective attempt by Sir Robert Graham to arrest him at a general council. James was assassinated at Perth on the night of 20/21 February 1437 during a failed coup by his uncle Walter Stewart, Earl of Atholl. Queen Joan, although wounded, managed to evade the attackers and reached her son — now King James II — in Edinburgh Castle.

Prince and Steward of Scotland
James was probably born in late July 1394 at Dunfermline Abbey, 27 years after the marriage of his parents, Robert III and Annabella Drummond. It was also at Dunfermline under his mother's care that James would have spent most of his early childhood. The prince was seven years old when his mother died in 1401, and a year later his elder brother David, Duke of Rothesay, was probably murdered by their uncle Robert Stewart, Duke of Albany, after being held at Albany's Falkland Castle. Prince James, now heir to the throne, was the only impediment to the transfer of the royal line to the Albany Stewarts. In 1402 Albany and his close ally Archibald, 4th Earl of Douglas, were absolved of any involvement in Rothesay's death, clearing the way for Albany's re-appointment as the king's lieutenant.



Albany rewarded Douglas for his support by allowing him to resume hostilities in the Kingdom of England. The Albany and Douglas affinity received a serious reversal in September 1402 when English troops defeated their large army at the Battle of Homildon Hill, and numerous Scottish nobles and their followers were captured. These included Douglas himself, Albany's son Murdoch, and the earls of Moray, Angus and Orkney. That same year, as well as the death of Rothesay, Alexander Leslie, Earl of Ross and Malcolm Drummond, Lord of Mar, had also died. The void created by these events was inevitably filled by lesser men who had not previously been conspicuously politically active. In the years between 1402 and 1406, the northern earldoms of Ross, Moray and Mar were without adult leadership and with Murdoch Stewart, the justiciar for the territory north of the Forth, being imprisoned in England, Albany found himself reluctantly having to ally with his brother Alexander Stewart, Earl of Buchan, and Buchan's son, also called Alexander, to hold back the ambitions of the Lord of the Isles. Douglas's absence from his power base in the Lothians and the Scottish Marches encouraged King Robert's close allies Henry Sinclair, Earl of Orkney, and Sir David Fleming of Biggar to take full advantage in becoming the principal political force in that region.

In December 1404 the king granted the royal Stewart lands in the west, in Ayrshire and around the Firth of Clyde, to James in regality, protecting them from outside interference and providing the prince with a territorial centre should the need arise. Yet in 1405, James was under the protection and tutelage of Bishop Henry Wardlaw of St Andrews on the country's east coast. The animosity of Douglas was intensifying because of the activities of Orkney and Fleming, who continued to expand their involvement in border politics and foreign relations with England. Although a decision to send the young prince to France and out of Albany's reach was taken in the winter of 1405–1406, James's departure from Scotland was unplanned. In February 1406 Bishop Wardlaw released James to Orkney and Fleming who, with their large force of Lothian adherents, proceeded into hostile Douglas east Lothian. James's custodians may have been displaying royal approval to further their interests in Douglas country. This provoked a fierce response from James Douglas of Balvenie and his supporters who, at a place called Long Hermiston Muir, engaged with and killed Fleming while Orkney and James escaped to the comparative safety of the Bass Rock islet in the Firth of Forth. They endured more than a month there before boarding the France-bound Maryenknyght, a ship from Danzig. On 22 March 1406, the ship was captured by an English vessel that was under the partial ownership of English politician Hugh Fenn; the vessel's crew delivered James to Henry IV of England, who kept him as a hostage. Robert III was at Rothesay Castle when he learned of his son's capture and he died soon after, on 4 April 1406, and was buried in the Stewart foundation abbey of Paisley.

King in captivity
James, now the uncrowned King of Scots, began what proved to be his 18-year period as a hostage while, simultaneously, Albany transitioned from lieutenant to governor. Albany took James's lands under his control, depriving the king of income and any of the regalia of his position, and was referred to in records as 'the son of the late king'. The king had a small household of Scots that included Henry Sinclair, Earl of Orkney, Alexander Seaton, the nephew of Sir David Fleming, and Orkney's brother John Sinclair, following the earl's return to Scotland. In time, James's household — now paid for by the English — changed from high-ranking individuals to less notable men. Henry IV treated the young James well, providing him with a good education.



James was ideally placed to observe Henry's methods of kingship and political control, having probably been admitted into the royal household upon reaching adulthood. James used personal visits from his nobles, coupled with letters to individuals, to maintain his visibility in his kingdom. Henry died in 1413 and his son, Henry V, immediately ended James's comparative freedom by initially holding him in the Tower of London along with the other Scottish prisoners. One of these prisoners was James's cousin, Murdoch Stewart, Albany's son, who had been captured in 1402 at the Battle of Homildon Hill. Initially held apart, from 1413 until Murdoch's release in 1415, they were together in the Tower and at Windsor Castle.

By 1420, James's standing at Henry V of England's court improved greatly; he ceased to be regarded as a hostage and more of a guest. James's value to Henry became apparent in 1420 when he accompanied Henry to France where his presence was used against the Scottish troops fighting alongside the French. Following the English victory at the siege of Melun, a town southeast of Paris, Scottish prisoners of war captured after the siege were hanged for treason against their king. James attended the coronation of Catherine of Valois on 23 February 1421 and was honoured by sitting immediately on the left of queen at the coronation banquet. In March, Henry began a circuit of the important towns in England as a show of strength, and during this tour James was knighted on Saint George's Day. By July, the two kings were back campaigning in France where James, evidently approving of Henry's methods of kingship, seemed content to endorse his claims to the French crown. Henry appointed the Duke of Bedford and James as the joint commanders of the siege of Dreux on 18 July 1421 and, on 20 August, they received the surrender of the garrison. Henry died of dysentery on 31 August 1422 and, in September, James was part of the escort taking Henry's body back to London.



The regency council of the infant Henry VI of England was inclined to have James released as soon as possible. In the early months of 1423, their attempts to resolve the issue met with little response from the Scots, clearly influenced by the Albany Stewarts and adherents. Archibald, Earl of Douglas was an astute and adaptable power in Southern Scotland whose influence even eclipsed that of the Albany Stewarts. Despite his complicity in James's brother's death in Albany's castle in 1402, Douglas could still engage with the king. From 1421, Douglas had been in regular contact with James and they formed an alliance that was to prove pivotal in 1423. Although Douglas was the pre-eminent Scottish magnate, his position in the borders and Lothians was jeopardised — not only did he have to forcibly retake Edinburgh Castle from his own designated warden, but was very likely under threat from the Earls of Angus and March. In return for James's endorsement of Douglas's position in the kingdom, the earl was able to deliver his affinity in the cause of the king's homecoming. Also, the relationship between Murdoch—now Duke of Albany following his father's death in 1420 — and his own appointee, Bishop William Lauder, seemed to be under strain, perhaps evidence of an influential grouping at odds with Murdoch's stance. Pressure from these advocates for the king almost certainly compelled Murdoch to agree to a general council in August 1423, where it was agreed that a mission should be sent to England to negotiate James's release. James's relationship with the House of Lancaster changed in February 1424 when he married Joan Beaufort, a cousin of Henry VI and the niece of Thomas Beaufort, 1st Duke of Exeter and Henry, Bishop of Winchester. A ransom treaty of £40,000 sterling (less a dowry remittance of 10,000 marks) was agreed at Durham on 28 March 1424, to which James attached his own seal. The king and queen, escorted by English and Scottish nobles, reached Melrose Abbey on 5 April and were met by Albany, who relinquished his governor's seal of office.

First acts


Throughout the 15th century, Scottish kings suffered from a lack of crown revenue and James's reign was no exception. The Albany regency had also been constrained, with Duke Robert being owed his fees of governorship. For the nobility, royal patronage ceased entirely following James's capture; irregular forms of political favours emerged, with Albany allowing nobles such as the earl of Douglas and his brother James to remove funds from the customs. It was against this backdrop that James's coronation took place at Scone on 21 May 1424. The coronation parliament of the Three Estates witnessed the king perform a knighthood ceremony for eighteen prominent nobles, including Alexander Stewart, Murdoch's son, an event probably intended to foster loyalty to the crown within the political community.

Called primarily to discuss issues surrounding the finance of the ransom payments, the parliament heard James underline his position and authority as monarch. He ensured the passing of legislation designed to substantially improve crown income by revoking the patronage of royal predecessors and guardians. The earls of Douglas and Mar were immediately affected by this when their ability to remove large sums from the customs was blocked.

Despite this, James was still dependent on the nobility—especially Douglas—for its support, and initially adopted a less confrontational stance. The early exception to this was Walter Stewart, Albany's son. Walter was the heir to the earldom of Lennox and had been in open revolt against his father in 1423 for not giving way to his younger brother Alexander for this title. He also disagreed with his father's acquiescence to the return of James to Scotland.

James had Walter arrested on 13 May 1424 and imprisoned on the Bass Rock—this was probably in Murdoch's interests as well as James's. The king probably felt unable to move against the rest of the Albany Stewarts, while Murdoch's brother, John Stewart, Earl of Buchan, and Archibald, 4th Earl of Douglas, were fighting against English forces in France. Buchan, a leader with an international reputation, commanded a large Scottish army, but both he and Douglas were killed by English troops at the Battle of Verneuil in August 1424 and the Scottish army was crushed. The loss of his brother with his large fighting force exposed Murdoch politically.

A ruthless and acquisitive king
The death of Douglas at Verneuil would also weaken his son Archibald, the fifth earl. On 12 October 1424, the king and Archibald met at Melrose Abbey, ostensibly to agree to the appointment of John Fogo, a monk of Melrose, to the abbacy. The meeting may also have been intended as an official acceptance of Douglas, but it signalled a change in the Black Douglas predominance vis-a-vis the crown and other nobles. Important Douglas allies died in France and some of their heirs realigned with rival nobles through blood ties, while at the same time, Douglas experienced a loosening of allegiances in the Lothians and, with the loss of his command over Edinburgh Castle, this all served to improve James's position. James continued to retain Black Douglas support, allowing him to begin a campaign of political alienation of Albany and his family. The king's bitterness, directed at Duke Murdoch, had its roots in the past—Duke Robert was responsible for his brother David's death. Moreover, neither Robert nor Murdoch exerted themselves in negotiating James's release and must have left the king with the suspicion that they held aspirations for the throne. Buchan's lands did not fall to the Albany Stewarts but were forfeited to the crown, Albany's father-in-law, Duncan, Earl of Lennox, was imprisoned, and in December, the duke's main ally, Alexander Stewart, 1st Earl of Mar, settled his differences with the king. An acrimonious sitting of parliament in March 1425 precipitated the arrest of Murdoch, Isabella, his wife, and his son Alexander — of Albany's other sons, Walter was already in prison and James, his youngest, also known as James the Fat, escaped into the Lennox.



James the Fat led the men of Lennox and Argyll in open rebellion against the crown and may have been what the king needed to bring a charge of treason against the Albany Stewarts. Murdoch, his sons Walter and Alexander, and Duncan, Earl of Lennox were in Stirling Castle for their trial on 18 May at a specially convened parliament. An assize of seven earls and fourteen lesser nobles was appointed to hear the evidence that linked the prisoners to the rebellion in the Lennox. The four men were condemned, Walter on 24 May and the others on 25 May, and immediately beheaded in 'front of the castle'. James demonstrated a ruthless and avaricious side to his nature in the destruction of his close family, the Albany Stewarts, that yielded the three forfeited earldoms of Fife, Menteith and Lennox. An inquiry set up by James in 1424 into the dispersal of crown estates since the reign of Robert I exposed legal defects in several transactions where the earldoms of Mar, March and Strathearn, together with the Black Douglas lordships of Selkirk and Wigtown, were found to be problematic. Strathearn and March were forfeited in 1427 and 1435, respectively. Mar was forfeited in 1435 on the earl's death without an heir, which also meant that the lordships of Garioch and Badenoch reverted to the crown. James sought to boost his income further through taxation and succeeded in getting parliament to pass legislation in 1424 for a tax to go towards paying off the ransom — £26,000 was raised but James sent only £12,000 to England. By 1429, James stopped the ransom payments completely and used the remainder of the taxation income on cannons and luxury goods from Flanders. Following a fire in the castle of Linlithgow in 1425, funds were also diverted to the building of Linlithgow Palace, which continued until James died in 1437, and absorbed an estimated one-tenth of royal income.

Relations with the church


James asserted his authority over the Church as well as the nobility and regretted that King David I's benevolence towards the Church proved costly to his successors and that he was "a sair sanct to the croun". James also considered that the monastic institutions in particular needed improvement and that they should return to being strictly ordered communities. Part of James's solution was to create an assembly of overseeing abbots and followed this up by establishing a Carthusian priory at Perth to provide other religious houses with an example of internal conduct. He also sought to influence church attitudes to his policies by having his own clerics appointed to the bishoprics of Dunblane, Dunkeld, Glasgow and Moray.

In March 1425, James's parliament directed that all bishops must instruct their clerics to offer up prayers for the king and his family; a year later, parliament toughened up this edict, insisting that the prayers be given at every mass, under the sanction of a fine and severe rebuke. This same parliament legislated that every person in Scotland should "be governed under the king's laws and statutes of this realm only". From this, laws were enacted in 1426 to restrict the actions of prelates whether it was to regulate their need to travel to the Roman Curia or their ability to purchase additional ecclesiastical positions while there. In James's parliament of July 1427, it is evident that the statute being enacted was to limit the authority of church jurisdiction.

On 25 July 1431, the general council of the Church convened in Basel, but the initial full meeting did not take place until 14 December l431, by which time Pope Eugene IV and the council were in complete disagreement. It was the council and not the pope who requested that James send representatives of the Scottish church, and it is known that two delegates — Abbot Thomas Livingston of Dundrenanan and John de Winchester, canon of Moray and a servant of the king — were in attendance in November and December 1432. In 1433 James, this time in response to a summons by the pope, appointed two bishops, two abbots and four dignitaries to attend the council. Twenty-eight Scottish ecclesiastics attended at intervals from 1434 to 1437, but the majority of the higher-ranking churchmen sent proxy attendees; Bishops John Cameron of Glasgow and John de Crannach of Brechin, however, attended in person, as did Abbot Patrick Wotherspoon of Holyrood. Even in the midst of the Basel general council, Pope Eugenius instructed his legate, Bishop Antonio Altan of Urbino, to meet with James to raise the issue of the king's controversial anti-barratry laws of 1426. The Bishop of Urbino arrived in Scotland in December 1436 and, apparently, a reconciliation between James and the papal legate had taken place by the middle of February 1437, but the events of 21 February, when James was assassinated, prevented the legate from completing his commission.

Highland problem
The king called a general council in July 1428 in Perth to raise funds for an expedition into the Highlands against the semi-autonomous Lord of the Isles. The council initially resisted granting James the funds — even with royal support from the powerful Earls of Mar and Atholl — but eventually gave in to the king's wishes. Although it seemed that an all-out attack on the Gaels of the north was not the king's intention, James had resolved to use a degree of force to strengthen royal authority. He told the assembly:

"I shall go and see whether they have fulfilled the required service; I shall go I say and I will not return while they default. I will chain them so that they are unable to stand and lie beneath my feet."

The leaders of the Gaelic kindreds in the north and west were summoned by James ostensibly to a sitting of parliament in Inverness. Of those assembled the king arrested around 50 of them including Alexander, the third Lord of the Isles, and his mother, Mariota, Countess of Ross, around 24 August. A few were executed but the remainder, except Alexander and his mother, were quickly released.

During Alexander's captivity, James attempted to split Clann Dòmhnall — Alexander's uncle John Mór was approached by an agent of the king to take the clan leadership but he refused to have any dealings with the king while his nephew was held prisoner led to John Mór's arrest and murder by the king's agent.



The king's need for allies in the west and north led him to soften his approach towards the Lord of the Isles and, hoping that Alexander would now become a loyal servant of the crown, he was given his freedom.

Alexander, probably under pressure from his close kinsmen Donald Balloch, John Mór's son, and Alasdair Carrach of Lochaber, led an attack on the castle and burgh of Inverness in the spring of 1429. The crisis deepened when a fleet from the Lordship was dispatched to bring James the Fat back from Ulster 'to convey him home that he might be king'. With James's intention to form an alliance with the Ulster O'Donnells of Tyreconnell against the MacDonalds, the English distrusted the Scottish king's motives and tried to bring James the Fat to England. Before he could become an active player, James the Fat died suddenly, releasing James to prepare for decisive action against the Lordship.

The armies met on 21 June in Lochaber and Alexander, suffering the defection of Clan Chattan (the MacKintoshes) and Clan Cameron, was heavily defeated. Alexander escaped probably to Islay but James continued his assault on the Lordship by taking the strongholds of Dingwall and Urquhart castles in July. The king pushed home his advantage when an army reinforced with artillery was dispatched to the Isles. Alexander probably realised that his position was hopeless and tried to negotiate terms of surrender but James demanded and received his total submission. From August 1429 the king delegated royal authority to Alexander Stewart, Earl of Mar to keep the peace in the north and west.

The Islesmen rose again in September 1431 and inflicted two important defeats on the king's men — Mar's army was beaten at Inverlochy and Angus Moray's in a fierce battle near Tongue in Caithness. This was a serious setback for James and his credibility was adversely affected.

In 1431, before the September uprising, the king had arrested two of his nephews, John Kennedy of Carrick and Archibald, Earl of Douglas, possibly because of a conflict between John and his uncle, Thomas Kennedy in which Douglas may have become involved. Douglas's arrest had raised tensions in the country and James acted to reduce the unrest by freeing the earl on 29 September — it was quite likely that the king made the earl's release conditional on support at the forthcoming parliament at Perth at which James intended to push for further funding for the campaign against the Lordship. Parliament was in no mood to allow James unconditional backing — he was allowed a tax to fund his Highland campaign but parliament retained full control over the levy. The rules parliament attached to the taxation indicated a robust stand against further conflict in the north and probably led to the turnaround that took place on 22 October when the king 'forgave the offence of each earl, namely Douglas and Ross [i.e. Alexander]'. For Douglas, this was a formal acknowledgement of his having been freed three weeks earlier, but for Alexander, this was a total reversal of crown policy towards the Lordship. Four summer campaigns against the Lordship were now officially at an end with James's wishes having effectively been blocked by parliament.

Foreign policy
James's release in 1424 did not herald a new phase relationship in Anglo-Scottish relations. Contrary to the English council's hopes, the king emerged as a confident and independently-minded European monarch. The only substantive matters of contention between the two kingdoms were the payments due under the terms of James's release and the renewal of the truce that would expire in 1430. In 1428 after setbacks on the battlefield Charles VII of France sent his ambassador Regnault de Chartres, Archbishop of Rheims to Scotland to persuade James to renew the Auld Alliance — the terms were to include the marriage of the princess Margaret to Louis, the dauphin of France, and a gift of the province of Saintonge to James. The ratification of the treaty by Charles took place in October 1428 and James, now with the intended marriage of his daughter into the French royal family and the possession of French lands, had his political importance in Europe boosted.



The effectiveness of the alliance with France had virtually ceased after Verneuil and its renewal in 1428 did not alter that — James adopted a much more non-aligned position with England, France and Burgundy while at the same time opening up diplomatic contacts with Aragon, Austria, Castile, Denmark, Milan, Naples and the Vatican.

Generally, Anglo-Scottish relations were relatively amicable and the truce, extended until 1436, helped the English position in France. Promises made in 1428 of a Scottish army to help Charles VII and the marriage of James's eldest daughter to the French king's son Louis were unrealised. James had to balance his European responses carefully, because England's key ally, the Duke of Burgundy, was in possession of the Low Countries, a major trading partner of Scotland causing James's support for France to be muted. The truce with England expired in May 1436, but James's perception of the Anglo-French conflict changed following a realignment of the combatants. The breakdown of the talks between England and France in 1435 precipitated an alliance between Burgundy and France, a request from France for Scottish involvement in the war, and for the fulfilment of the promised marriage of Princess Margaret to the Dauphin.

In the spring of 1436 Princess Margaret sailed to France, and in August Scotland entered the war, with James leading a large army to lay siege to the English enclave of Roxburgh Castle. The campaign was to prove pivotal, the Book of Pluscarden describes ' a detestable split and most unworthy difference arising from jealosy ' within the Scottish camp and the historian Michael Brown explains that a contemporary source has James appointing his young and inexperienced cousin, Robert Stewart of Atholl, as the constable of the host ahead of the experienced march wardens, the earls of Douglas and Angus. Brown explains that both earls possessed considerable local interests and that the effects of such a large army living off the land may have created resentment and hostility in the area. When the militant prelates of York and Durham, together with the Earl of Northumberland, took their forces into the marches to relieve the fortress, the Scots swiftly retreated—a chronicle written a year later said that the Scots 'had fled wretchedly and ignominiously' — but what is certain is that the effects and manner of the defeat, together with the loss of their expensive artillery, was a major reversal for James both in terms of foreign policy and internal authority.

Background
Walter Stewart was the youngest of Robert II's sons and the only one not to have been provided with an earldom during his father's lifetime. Walter's brother, David, Earl of Strathearn and Caithness, had died before 5 March 1389 when his daughter Euphemia was first recorded as Countess of Strathearn. Walter, now guardian of his niece, administered Strathearn for the next decade and a half, during which time he aided his brother Robert, Earl of Fife and Guardian of Scotland, by enforcing law and order upon another brother, Alexander, lord of Badenoch — he again supported Robert (now Duke of Albany) against their nephew, David, Duke of Rothesay in 1402. Albany most likely engineered the marriage of Euphemia to one of his affinity, Patrick Graham, and, by doing so, ended Walter's involvement in Strathearn. Duke Robert, possibly to make up for the loss of the benefits of Strathearn, made Walter Earl of Atholl and Lord of Methven. In 1413, Graham was killed in a quarrel with his own principal servant in the earldom, John Drummond.



The Drummond kindred was close to Atholl and the Earl's renewed involvement in Strathearn as ward to Graham's son, despite strong opposition from Albany, hinted at Atholl's possible involvement in the murder. The bad blood now existing between Albany and Atholl led James on his return to Scotland in 1424 to ally himself with Earl Walter, his uncle. Atholl participated at the assize that sat over the 24/25 May 1425 trials which found the prominent members of the Albany Stewarts guilty of rebellion — their executions followed swiftly.

James granted Atholl the positions of Sheriff of Perth and Justiciar, as well as the earldom of Strathearn, but this, significantly, in life-use only, acts that confirmed Earl Walter's policing remit given by Albany, and his already effective grip on Strathearn. Atholl's elder son, David, had been one of the hostages sent to England as a condition of James's release and had died there in 1434; his younger son Alan died in the king's service at the Battle of Inverlochy in 1431. David's son Robert was now Atholl's heir and both were now in line to the throne after the young Prince James. James continued to show favour to Atholl and appointed his grandson Robert as his personal chamberlain, but by 1437 after a series of setbacks at the hands of James, the earl and Robert probably viewed the king's actions as a prelude to further acquisitions at Atholl's expense. Atholl's authority over the wealthy earldom of Strathearn was tenuous, and both he and Robert would have realised that Strathearn would have returned to the crown upon Atholl's death. This meant that Robert's holdings would have been the relatively impoverished earldoms of Caithness and Atholl and amounted to no more than what was in Earl Walter's possession in the years between 1406 and 1416.

The retreat from Roxburgh exposed the king to questions regarding his control over his subjects, his military competence and his diplomatic abilities yet he remained determined to continue with the war against England. Just two months after the Roxburgh fiasco, James called a general council in October 1436 to finance further hostilities through more taxation. The estates firmly resisted this and their opposition was articulated by their speaker Sir Robert Graham, a former Albany attendant but now a servant of Atholl. The council then witnessed an unsuccessful attempt by Graham to arrest the king resulting in the knight's imprisonment followed by banishment but James failed to see Graham's actions as part of an extended threat. In January 1437, Atholl received yet another rebuff in his own heartlands when James overturned the chapter of Dunkeld Cathedral whose nominee was replaced by the king's nephew and firm supporter, James Kennedy.

Conspiracy and regicide


The reaction against the king at the general council had shown Atholl that not only was James on the back foot but his political standing had received a huge setback and may have convinced the earl that James's killing was now a viable course of action. Atholl had seen how assertive action by two of his brothers at different times had allowed them to take control of the kingdom and that as James's nearest adult relative, the earl must have considered that decisive intervention on his part at this time could prove to be equally successful.

The conspiracy against the king seems to have been heavily influenced by the Albany Stewarts' destruction in 1425. Their judicial killing and forfeiture of their lands influenced the servants who administered and depended on these estates for their living. Atholl, under whose service several of these disgruntled Albany men appear, filled the void created by this. Among them were the brothers Robert and Christopher Chambers, and Sir Robert Graham, who only three months before had tried to arrest the king at the Perth council. Even though Robert Chambers was a member of the Royal household, the old Albany ties were stronger.

A general council was held in Atholl's heartland in Perth on 4 February 1437 and crucially for the conspirators, the king and queen had remained in the town at their lodgings in the Blackfriars monastery. In the evening of 20 February 1437 the king and queen were in their rooms and separated from most of their servants. Atholl's grandson and heir Robert Stewart, the king's chamberlain, allowed his co-conspirators — thought to number about thirty and led by Robert Graham and the Chambers brothers — access to the building. James was alerted to the men's presence, giving the king time to hide in a sewer tunnel, but with its exit recently blocked off to prevent tennis balls getting lost, James was trapped and murdered.

Aftermath
The assassins had achieved their priority in killing the king but the queen, although wounded, had escaped. Importantly, the six-year-old prince, now King James II, had been safeguarded from Atholl's control by the removal of the earl's associate, John Spens, from his role as James's custodian. Spens vanished from the records following the regicide but the re-allocation of his positions and lands immediately following the murder indicate his part in the plot. Yet, in the chaos following the murder, it appeared that the queen's attempt to position herself as regent was not guaranteed.

No surviving documentation exists that suggests that there was any general feeling of horror or condemnation aimed at the murderers. Possibly had the botched attempt at killing the queen succeeded and had Atholl taken control of the young king his attempted coup might have succeeded. The queen's small group of loyal supporters including the Earl of Angus and William Crichton ensured her continued hold of James. This in itself greatly reinforced her situation but Atholl still had followers. By the first week of March, neither side seemed to have the ascendancy and the Bishop of Urbino, the pope's envoy, called for the council to pursue a peaceful outcome.

Despite this, by the middle of March, both Angus and Crichton had probably mobilised to move against Atholl. It is equally likely that Atholl had gathered his forces to resist incursions into his heartlands — on 7 March the queen and the council entreated the burgess' of Perth to resist the forces of the "feloune traitors".

The position of Atholl and his circle of close supporters only collapsed after Earl Walter's heir Robert Stewart had been captured and who, in Shirley's account, confessed to his part in the crime. Walter was taken prisoner by Angus and held at the Edinburgh Tolbooth where he was tried and beheaded on 26 March 1437, the day after the coronation of the young James II. Sir Robert Graham, the leader of the band of assassins, was captured by former Atholl allies and was tried at a session of the council sitting at Stirling Castle and subsequently executed sometime shortly after 9 April.

Queen Joan's pursuit of the regency ended probably at the council of June 1437 when Archibald, 5th Earl of Douglas, was appointed lieutenant-general of the kingdom.

King James's embalmed heart may have been taken on a pilgrimage to the Holy Land following his interment at Perth Charterhouse, as the Exchequer Rolls of Scotland for 1443 note the payment of £90 to cover the costs of a knight of the Order of St John who had returned it to the Charterhouse from the Island of Rhodes.

Historiography
James was a paradoxical figure. Although a prisoner of England he still received a good education and developed into a cultured individual becoming a poet, an accomplished musician and skilled in sports. Walter Bower, abbot of Inchcolm, lists James's qualities as a musician — "not just as an enthusiastic amateur" but a master, "another Orpheus". His mastery included the organ, drum, flute and lyre. James's sporting abilities such as wrestling, hammer throwing, archery and jousting are also listed by Bower. He described James as possessing an 'eagerness' in 'literary composition and writing', the best known of which is his love poem, The Kingis Quair. Bower characterised the king as "a tower, a lion, a light, a jewel, a pillar and a leader "and was our law giver king" who ended the 'thieving, dishonest conduct and plundering".

Abbot Bower also described the king as capable of stabbing a near relative through the hand for creating a disturbance at court. The abbot was generally supportive of James but he and others regretted the demise of the Albany Stewarts, and he was confounded by James's greed for territory and wealth. Although Bower did not dwell at length on the negative aspects of James's character, he alluded to the dismay of even those close to the king at his harsh regime. John Shirley's account of the events leading up to James's murder in the work The Dethe of the Kynge of Scotis provided an accurate narrative of politics in Scotland and which must have depended upon knowledgeable witnesses. The Dethe describes James as "tyrannous" and whose actions were motivated by revenge and "covetise ... than for anny laweful cawse". Shirley agrees with Bower as far as the Albany Stewarts were concerned when he wrote that the Albanys whos dethe the people of the land sore grutched and mowrned. Writing nearly a century later both the chroniclers John Mair and Hector Boece relied extensively on Bower for their own narratives. They described James as the embodiment of good monarchy with Mair's eulogy that James "...indeed excelled by far in virtue his father, grandfather and his great-grandfather nor will I give precedence over the first James to any of the Stewarts", while Boece, in a similar vein, calls James the maist vertuous Prince that evir was afoir his days. Late in the 16th century the early historians George Buchanan and Bishop John Lesley from opposite ends of the religious spectrum both looked favourably on James's reign but were uneasily mindful of an enduring aggressive history regarding the king.

The first 20th century history of James I was written by E.W.M. Balfour-Melville in 1936 and continued the theme of James as the strong upholder of law and order and, when describing Albany's trial and execution, he writes "the King had proved that high rank was no defence for lawlessness; the crown was enriched by the revenues of Fife, Menteith and Lennox". Balfour-Melville views James as a lawmaker and a "reformer" whose legislation was aimed at not only increasing the position of the king but of parliament. Michael Lynch describes how James's positive reputation began immediately after his death when the Bishop of Urbino kissed James's wounds and declared him to be a martyr. He suggests that the praise of the pro-James Scottish chroniclers and also of some modern historians to "find strong king to applaud" should not diminish the extent of parliament's ability to restrain the king nor minimise the confrontation that took place between James and a more self-assured parliament. Stephen Boardman takes the view that by the time of his death James had succeeded in breaking down the constraints on the exercise of royal authority which were rooted in the "settlement of the kingdom" by Robert II. Christine McGladdery describes how opposing views were the result of "competing propaganda after the murder". To those who were glad to see the king dead, James was a tyrant who, without reason, aggressively assailed the nobility, imposing forfeiture on their estates and who "failed to deliver justice to his people". She also provides the opposite viewpoint that the king was seen as giving "strong leadership against magnate excesses" and that the murder "was a disaster for the Scottish people, leaving them to endure the instability of years of consequent faction fighting". McGladdery continues that James was the example for the Stewart kings to follow by putting "Scotland firmly within a European context".

Michael Brown describes James as an "able, aggressive and opportunistic politician" whose chief aim was to establish a monarchy that had stature and was free from the confrontations that had beset his father's reign. He characterises James as "capable of highly effective short-term interventions" yet has failed to achieve a position of unqualified authority. Brown writes that James had come to power after "fifty years when kings looked like magnates and magnates acted like kings" and succeeded in completely changing the outlook and objectives of the monarchy. His policy of reducing the power and influence of the magnates, continued by his son James II, led to a more subordinate nobility. Alexander Grant repudiates James's reputation as the "law giver" and explains that nearly all of the king's legislation were reconstructions of laws laid down by previous monarchs and concludes that "the idea of James's return in 1424 marks a turning point in the development of Scots law is an exaggeration". At James's death, only the Douglases of the predominant magnate houses were left and, according to Grant, this reduction was the most far-reaching change to the nobility and was "by far the most important consequence of James I's reign".

Marriage and issue
