Alexios Palaiologos
Alexios Palaiologos (died 1203) was a Byzantine nobleman, son of the megas hetaireiarches George Palaiologos. In spring 1199 Emperor Alexios III Angelos, who had no son, married him to his widowed eldest daughter Irene Angelina and named him despot and heir.
He helped lure the rebel Ivanko to his execution in 1200 and crushed the coup of John Komnenos the Fat in July 1201. He died in 1203, before the Fourth Crusade reached Constantinople; through his daughter Theodora he was an ancestor of the Palaiologan dynasty.
