regent of Antioch, one of the leaders of the First Crusade (Crusades).

Tancred was a Norman lord of south Italy. He went on the Crusade with his uncle, Bohemond (the future Bohemond I of Antioch), and first distinguished himself in Cilicia, where he captured Tarsus from the Turks and came into conflict with his fellow Crusader, Baldwin of Boulogne. He played a prominent part in most of the major battles of the Crusade, and after the capture of Jerusalem (1099) he received the title Prince of Galilee. He served as regent of the principality of Antioch for Bohemond while the latter was a prisoner of the Turks (1101–03) and controlled Antioch permanently after Bohemond returned to Europe in 1104.

As regent of Antioch, and also of Edessa from 1104 to 1108, Tancred became the chief Latin magnate of northern Syria, engaging in continual warfare with both the Turks and the Byzantines until his death. The portrayal of Tancred by Torquato Tasso in the Italian epic poem Gerusalemme liberata (1581; “Jerusalem Delivered”) is largely imaginary.
