Syrgiannes Palaiologos Philanthropenos

Syrgiannes Palaiologos Philanthropenos (c. 1290–1334) was a Byzantine general, born to a Cuman chief and a niece of Michael VIII. In the civil war between Andronikos II and Andronikos III, he backed the grandson in 1321, helped force a partition, defected that December, and was jailed for plotting to seize the throne.

Pardoned, he governed Thessalonica from 1329, fled to Stefan Dušan of Serbia in 1334, and led Serbian troops that overran much of Macedonia. Later that year he was lured out and murdered by Sphrantzes Palaiologos.
