Alexios III Angelos
Alexios III Angelos (c. 1153–1211) was Byzantine emperor from 1195 to 1203. His brother Isaac II made him sebastokrator, but in 1195 Alexios seized Isaac, blinded and imprisoned him.
His reign saw lavish gifts that emptied the treasury and plundered imperial tombs for tribute. Turkish and Bulgarian raids went unchecked.
When the Fourth Crusade stormed Constantinople for Alexios IV in July 1203, he fled by night. He blinded Alexios V, fell captive to Boniface of Montferrat, and in 1211 was taken fighting his son-in-law Theodore I Laskaris; he died in a Nicaean monastery.
