Duchy of Apulia and Calabria in the context of "Norman people"

The Principality of Antioch (Latin: Principatus Antiochenus; Norman: Princeté de Antioch) was one of the Crusader states created during the First Crusade which included parts of Anatolia (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 Duchy of Apulia and Calabria in 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.
