Year 1105 (MCV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar.

Levant

 * February 28 – Raymond IV dies at his castle of Mons Peregrinus ("Pilgrim's Mountain") near Tripoli. Raymond leaves his 2-year-old son Alfonso I by his third wife, Elvira of Castile, to rule the County of Tripoli. Raymond's nephew William-Jordan, count of Cerdagne, becomes regent over Alfonso. Bertrand, the eldest son of Raymond, inherits the title 'Count of Toulouse'.
 * April 20 – Battle of Artah: The Crusaders under Tancred, Norman prince and regent of Antioch, defeat a Seljuk army (some 7,000 men) at Artah (modern-day Reyhanlı). Tancred threatens Aleppo, capital of Sultan Fakhr al-Mulk Radwan, and expands his conquest by conquering more territory east of the Orontes River with minor opposition.
 * August 27 – Battle of Ramla: The Crusaders under King Baldwin I defeat a Fatimid expeditionary force (some 15,000 men) at Ramla. Baldwin pillages the enemy camp – but does not further pursue the Fatimids. The battle ends in the last large-scale attempt of the Fatimids to reconquer Palestine.

Europe

 * The Almoravid emir, Yusuf ibn Tashfin, sends a maritime expedition to Palestine from Sevilla to ward off the Crusaders and perhaps to reconquer Jerusalem. The fleet of about seventy ships rushes into a storm in the Mediterranean Sea, and is never seen again.
 * Bohemond I, Norman prince of Antioch, arrives in Apulia (Southern Italy) after an absence of 9 years. He travels to Rome and meets Pope Paschal II. His cousin, Roger II becomes count of Sicily.
 * Autumn – Bohemond I and papal legate Bruno travel to the north of France and visit the court of King Philip I (the Amorous). Bohemond gets permission to recruit men throughout the kingdom.
 * Inge the Elder dies and is succeeded by his nephew Philip as ruler of Sweden. He and his brother Inge the Younger rule the kingdom together (until the death of Philip in 1118).
 * December 31 – Emperor Henry IV is deposed by his son Henry V (who is king of Germany). Henry is forced to resign his crown and is imprisoned in the castle of Böckelheim.

England

 * Summer – King Henry I invades Normandy, takes Bayeux (after a short siege) and Caen. He advances on Falaise, and starts inconclusive peace negotiations with Duke Robert II. Henry withdraws to deal with political issues at home.
 * Henry I meets Anselm, archbishop of Canterbury, under threat of excommunication at L'Aigle in Normandy to settle their disputes that has led to Anselm's exile from England (see 1103).

Seljuk Empire

 * Sultan Barkiyaruq dies in Borujerd (modern Iran) after a 13-year reign. He is succeeded by his son Malik-Shah II, but is deposed and killed by his uncle Muhammad I. Muhammad becomes ruler of the Seljuk Empire, but his brother Ahmad Sanjar (Seljuk ruler of Khorasan) holds more power as co-ruler.
 * Autumn – Kilij Arslan I, sultan of the Sultanate of Rum, leads a Seljuk expedition to take over Melitene (modern Turkey). He attempts to capture Edessa, but the Crusader fortress is too strongly defended by its garrison. Kilij Arslan then moves on to Harran, which surrenders to him.
