Great Troubles

The Great Troubles (Великая замятня, as found in Rus' chronicles), also known as the Golden Horde Dynastic War, was a war of succession in the Golden Horde from 1359 to 1381.

This era, which followed shortly after the Black Death had ravaged the cities of the Golden Horde, was characterised by two decades of near anarchy. A long series of short-reigning khans deposed and killed each other, only to suffer the same fate next. Mamai emerged as the most powerful Mongol warlord, frequently employing Rus' principalities such as Tver and Ryazan as his allies. Because he was not a Chingisid (descendant of Genghis Khan), Mamai had no legitimate claim to the throne, and instead used Chingisid puppet-khans to exercise political control.

The Rus' principalities and neighbouring states frequently changed their allegiancies at this time, joining forces with or against various Mongol factions and with or against each other, in tactical efforts to exploit rapidly shifting situations. The Grand Duchy of Lithuania as well as Horde vassals such as Tver and Muscovy were opportunistic in profiting from the internecine warfare that weakened Mongol-Tatar control in the region. Algirdas defeated Mamai's forces at the Battle of Blue Waters and thereby conquered the Principality of Kiev, while Dmitry Donskoy successfully united most Rus' princes against Mamai at the 1380 Battle of Kulikovo, solidifying Muscovite pre-eminence amongst them. However, Tokhtamysh's lightning rise to power in the late 1370s, his definitive victory over Mamai (1381) and subsequent sack of Moscow (1382) confirmed the Rus' principalities' vassalage to the Golden Horde.

Background
The Golden Horde had reached the height of its power and prosperity under Özbeg Khan ((r. 1313 – 1341)), when overland trade from the Black Sea to Yuan dynasty China flourished. While Özbeg adopted Islam, the Orthodox Church (exempt from taxes through yarliks or patents) continued supporting his rule, and the Turco-Mongolian population of his realm gradually assimilated and became known as "Tatars".

Taxes regularly collected by the darughachi or basqaq (baskak) from the subordinate Rus' principalities provided the Horde's coffers with plenty revenue. The responsibility of tax collection was eventually transferred from the basqaq to the Rus' princes, although it is unclear when this happened, or why, though the Golden Horde officials authorised with collecting the taxes were widely hated in Rus' sources. The last references to the basqaq system are found from the 1350s to 1382 in the Principality of Ryazan (possibly the last region to switch to princely tax collection), while emir Mamai is said to have intended to restore the basqaq system around 1380, indicating that it had fallen into disuse by then.

The khans obtained the prerogative of granting the title of Grand Prince of Vladimir to any Rus' prince they favoured through a yarlik (patent). They employed this highly symbolic title to prop up a weaker Rus' principality (usually Muscovy) against a stronger one (usually Tver) to keep the latter in check as a divide and rule policy. The Principality of Nizhny Novgorod-Suzdal also played this power game according to the Mongol rules in 1353 and 1371. In the mid-14th century, Algirdas (Olgerd) of Lithuania would try to bring Tver and Ryazan under his control during the Lithuanian–Muscovite War (1368–1372), and also played by the Mongol rules by sending a delegation to Golden Horde (as the neutral power-broker) in order to negotiate peace. But the Mongols used Moscow to counterbalance the rise of Lithuanian power; they arrested the Lithuanian envoys and handed them over to the Muscovites, so that Algirdas had to ransom his emissaries from his enemies.

Two developments in the mid-14th century were catastrophic for the Horde's society and economy: several Mongol khanates fell between 1330 and 1370, and the Black Death reached the capital city of Sarai in the 1340s, spreading to all urban centres of Golden Horde and its vassals, with many in the ranks of the khan's army and up to 25% of the Rus' population dying to the pandemic. The end of Özbeg Khan's reign in 1341 also sparked a series of dynastic regicides, first intermittently, then from 1359 with alarming frequency. Özbeg's son Tini Beg was murdered by his brother Jani Beg (1342), who in turn was possibly killed by his son Berdi Beg (1357). The latter's assassination by his brother Qulpa in 1359 is usually considered the start of the Great Troubles. When Qulpa was killed (1360) by yet another brother, Nawruz Beg, who himself died under suspicious circumstances after a year on the throne, the lineage of Batu Khan (the 1242 founder of the Golden Horde) went extinct. From 1360 to 1380, competing branches of the Jochid clan fought bitterly over the fate of the dynasty, while no fewer than 24 khans (possibly even more) were enthroned. The capital city of Sarai changed hands multiple times, in one year being successively conquered by 6 different pretenders.

1359–1360
Khan Berdi Beg (Berdibek) was killed in 1359 in a coup by his brother Qulpa. Qulpa's two sons were Christians and bore the Slavic names Michael and Ivan, which outraged the Muslim populace of the Golden Horde. In 1360, Qulpa's brother Nawruz Beg (Navruz) revolted against the khan and killed him and his sons.

When Rus' princes heard of Berdi Beg's death, they had begun travelling to Sarai to receive patents from his successor, but by the time they arrived, Nawruz had already assumed the throne. Nawruz did not award the title of Grand Prince of Vladimir to Muscovite prince Dmitry Ivanovich (later known as "Donskoy"), but to Dmitry Konstantinovich of Suzdal, the prince of Nizhny Novgorod–Suzdal, nephew of Alexander of Suzdal who previously held it (before Ivan I "Kalita" of Moscow). Dmitry Konstantinovich was part of a group of Rus' princes who were concerned about the rise of the Daniilovichi princely dynasty of Muscovy; the princes of Rostov, Beloozero, and Galich–Dmitrov supported Konstantinovich's claim to grand prince in return for receiving extra power for themselves from Nawruz. Nawruz was overthrown in 1361, however.

By 1360, Urus Khan had set up court in Sighnaq (near modern Shieli, Kazakhstan). He was named Urus, which means "Russian" in the Turkish language, presumably because "Urus-Khan's mother was a Russian princess... he was prepared to press his claims on Russia on that ground."

1360s
In 1361, a descendant of Shiban (5th son of Jochi), was invited by some grandees to seize the throne. Khidr rebelled against Nawruz, whose own lieutenant betrayed him and handed him over to be executed. Khidr was slain by his own son, Timur Khwaja, in the same year. Timur Khwaja reigned for only five weeks before descendants of Öz Beg Khan seized power.

In 1362, the Golden Horde was divided between Keldi Beg in Sarai, Bulat Temir in Volga Bulgaria, and Abdullah in Crimea. Meanwhile, the Grand Duchy of Lithuania attacked the western tributaries of the Golden Horde and conquered Kyiv and Podolia after the Battle of Blue Waters in 1363. A powerful Mongol general by the name of Mamai backed Abdullah but failed to take Sarai, which saw the reign of two more khans, Murad and Aziz. Abdullah died in 1370 and Muhammad Bolaq was enthroned as puppet khan by Mamai.

1370s
Mamai also had to deal with a rebellion in Nizhny Novgorod. Muscovite troops impinged on the Bulgar territory of Arab-Shah, the son of Bulat Temir, who caught them off guard and defeated them on the banks of the Pyana River (1377). However Arab-Shah was unable to take advantage of the situation because of the advance of another Mongol general from the east. Mamai sent an army against the Muscovite alliance in 1378, but Dmitri Donskoy defeated Mamai's forces led by general Begich at the Battle of the Vozha River.

In 1372, Urus marched west and occupied Sarai. His nephew and lieutenant Tokhtamysh deserted him and went to Timur for assistance. Tokhtamysh attacked Urus, killing his son Kutlug-Buka, but lost the battle and fled to Samarkand. Soon after, another general Edigu deserted Urus and went over to Timur. Timur personally attacked Urus in 1376 but the campaign ended indecisively. Urus died the next year and was succeeded by his son, Timur-Melik, who immediately lost Sighnaq to Tokhtamysh. In 1378, Tokhtamysh conquered Sarai.

1380–1381
By the 1380s, the Shaybanids and Qashan attempted to break free of the Khan's power.

Mamai hired Genoese, Circassian, and Alan mercenaries for another attack on Moscow in 1380. In the ensuing battle, Mongol forces once again lost at the Battle of Kulikovo.

The Great Troubles came to an end when Tokhtamysh personally defeated Mamai the Battle of the Kalka River (1381) to become the undisputed khan of the Golden Horde.

Aftermath: 1382 siege of Moscow
The siege of Moscow in 1382 was motivated by khan Tokhtamysh's desire to punish Muscovy for its audacity to challenge the authority of the Golden Horde at the Battle of Kulikovo (1380). Even though it was his rival warlord Mamai who was defeated at Kulikovo, and Tokhtamysh personally defeated Mamai at the Kalka River (1381) to become the undisputed khan, he wanted to make Moscow an example of what happened if anyone dared defy Mongol supremacy over the Rus' principalities. Tokhtamysh allied himself (in part through coercion) with the Rus' princes of Tver, Riazan, and Nizhniy Novgorod against Muscovy, and launched a surprise attack on the city in 1382. Prince Dmitry Donskoy, who had led his largely Muscovite army to a pyrrhic victory at Kulikovo two years earlier, abandoned his capital and fled north, leaving the dismayed citizens of Moscow to ask a Lithuanian prince named Ostei (or Ostej), a grandson of Algirdas, to lead the defence. The princes of Nizhniy Novgorod tricked the population into surrendering the city, after which Tokhtamysh' forces immediately sacked Moscow as punishment for resisting Mongol authority.

Although Kulikovo had marked Muscovy's new position as the pre-eminent state amongst the Rus' principalities, the subsequent sack of Moscow confirmed that Donskoy and the other princes remained firmly under suzerainty of the Tatar–Mongol Golden Horde, now ruled by Tokhtamysh. According to Halperin (1987), 'Moscow benefited more from the deteriorating relations between Tokhtamysh [and] Tamerlane (Timur) than it had from the victory of Kulikovo.' The Tokhtamysh–Timur war (1386–1395) and the 1399 Battle of the Vorskla River established Timurid control over the Golden Horde and its Rus' vassals, but because Muscovy mostly escaped the destruction of war, these years allowed it to recover and grow its strength.

Halperin (2016) described the Juchid ulus (Golden Horde) as having evolved from "the thirteenth to early fourteenth century major European and Asian power" to a "late fourteenth-century minor regional East European [power]" during the decades-long war. Tokhtamysh was not as bloodthirsty as Genghis Khan, and did not have the means to completely level Moscow (as Genghis would have done), just like Özbeg Khan had not wiped Tver from the face of the earth after crushing the Tver Uprising of 1327.
