The Principality of Antioch was one of the crusader states created during the First Crusade which included parts of modern-day Turkey and Syria. The principality was much smaller than the County of Edessa or the Kingdom of Jerusalem. It extended around the northeastern edge of the Mediterranean, bordering the County of Tripoli to the south, Edessa to the east, and the Byzantine Empire or the Kingdom of Armenia to the northwest, depending on the date.
It had roughly 20,000 inhabitants in the 12th century, most of whom were Armenians and Greek Orthodox Christians, with a few Muslims outside the Antioch city itself. Most of the crusaders who settled there were of Norman origin, notably from the Norman Kingdom of southern Italy, as were the first rulers of the principality, who surrounded themselves with loyal subjects. Few of the inhabitants apart from the Crusaders were Roman Catholic even though the city was under the jurisdiction of the Latin Patriarchate of Antioch, established in 1100. This patriarchate would endure as a titular one after the Crusades, until it was dropped in 1964.
Timeline of the Principality of Antioch and Antioch
The city of Antioch had been a major Byzantine stronghold in the area under the control of a doux before falling to the Seljuk Turks in 1084. Therefore, it was one of the cities the army of the First Crusade aimed to liberate on their way to Jerusalem. While Baldwin of Boulogne headed east from Asia Minor to set up the County of Edessa, the main army of the First Crusade continued south to besiege Antioch in late October 1097. The army consisted of various leaders who had sworn to return all territory that had belonged to the Byzantine Empire as well as a Byzantine contingent under the command of the general Tatikios. With over four hundred towers, the city's defenses were formidable. The siege lasted throughout the winter, with much attrition among the Crusader force, who were often forced to eat their horses, or, as legend has it, the bodies of all fellow Christians who had not survived.
