February 9–Battle of the Lake of Antioch: The Crusaders under Bohemond I defeat a Seljuk relief force (some 12,000 men) led by Sultan Fakhr al-Mulk Radwan of Aleppo. Bohemond gathers 700 knights, and marches in the night to ambush the Seljuk Turks at the Lake of Antioch (modern Turkey). After several successful cavalry charges the Crusaders rout the Seljuk army, forcing Radwan to retreat back to Aleppo.[1]
March 10–Baldwin of Boulogne enters Edessa, and is welcomed as liberator by the Armenian clergy. The local population massacres the Seljuk garrison and officials – or forces them to flee. Baldwin is acknowledged as their ruler (or doux). He assumes the title of count and establishes the first crusader state. Baldwin marries Arda of Armenia, daughter of Lord Thoros of Marash, and consolidates his conquered territory.[2]
June 3–Siege of Antioch: The Crusaders under Bohemond I capture Antioch after a 8-month siege. He established secret contact with Firouz, an Armenian guard who controlled the "Tower of the Two Sisters". He opened the gates and Bohemond entered the city. Thousands of Christians are massacred along with Muslims. Bohemond is named Prince of Antioch (under protest) and creates the Principality of Antioch.[3]
June 5–Battle of Antioch: Emir Kerbogha, ruler (atabeg) of Mosul, arrives at Antioch with a Seljuk army (35,000 men) to relieve the city. He lays siege to the Crusaders who have just captured the city themselves (although they do not have full control of it). A Byzantine relief force led by Emperor Alexios I Komnenos turns back after Count Stephen of Blois convinces them that the situation in Antioch is hopeless.[4]
June 28– Following the Holy Lance discovery by Peter Bartholomew in Antioch, the Crusaders under Bohemond I (leaving only 200 men) sortie from the city and defeat the Seljuk army. Kerbogha is forced to withdraw to Mosul, the garrison in the citadel surrenders to Bohemond personally (who raises his banner above the city) and the Crusaders occupy Antioch. The Crusade is delayed for the rest of the year.[5]
July 14– Donation of Altavilla: Bohemond I grants commercial privileges and the right to use warehouses (fondaco) to the Republic of Genoa. This marks the beginning of Italian merchant settlements in the Levant.[6]
December 12–Siege of Ma'arra: The Crusaders capture the city of Ma'arra after a month's siege and massacre part of the population. Short of supplies, the army is accused of widespread cannibalism.
