Manuel I Komnenos
Manuel I Komnenos was the most ambitious and westward-looking of the Komnenian emperors, a brilliant, energetic ruler whose expansive vision for Byzantine primacy across the Mediterranean world ultimately overreached the empire's resources and left it weakened at his death. He was the youngest son of John II, chosen on his deathbed, and reigned for 37 years. Manuel was deeply influenced by western chivalric culture - he jousted, wore western armor, favored Latin nobles at his court, and married a Latin princess, Bertha of Sulzbach. He dreamed of reunifying Christendom under Byzantine leadership and worked through an active western diplomacy involving marriage alliances, subsidies, and military intervention in Italy. He managed complex relations with the Crusader states, playing Antioch, Jerusalem, and Egypt against each other. In 1176, the Seljuks ambushed and devastated his army at Myriokephalon in a pass in Phrygia, a catastrophic defeat that shattered his army. As Manuel himself reportedly said, it was comparable to Manzikert. He died in September 1180 leaving an eleven-year-old heir, and the over-extension of his reign's commitments contributed directly to the crisis that destroyed the Komnenian dynasty.
