Alexios III was a Byzantine Emperor who ruled from 1195 to 1203. He came to power after deposing his brother, Isaac II Angelos, and faced numerous challenges, including military threats from the Seljuk Turks and internal strife within the empire. His reign was marked by political instability and economic decline. In 1203, Alexios III was overthrown by a coalition of nobles and the Fourth Crusade, leading to the establishment of the Latin Empire. He fled to Thessalonica and later to Asia Minor, where he lived until his death. His reign is often viewed as a period of decline for the Byzantine Empire.
