Alexios III attempted to escape Boniface's "protection" in 1205, seeking shelter with Michael I Komnenos Doukas, the ruler of Epirus. Captured by Boniface, Alexios and his retinue were sent to Montferrat before being brought back to Thessalonica in . At that point the deposed emperor was ransomed by Michael I, who sent him to Asia Minor, where Alexios' son-in-law Theodore Laskaris - now emperor of Nicaea - was holding his own against the Latins. Here Alexios conspired against his son-in-law after the latter refused to recognize Alexios' authority, receiving the support of Kaykhusraw I, the sultan of Rûm. In the Battle of Antioch on the Meander in 1211, the sultan was defeated and killed, and Alexios was captured by Theodore Laskaris. Alexios was then confined to a monastery at Nicaea, where he died later in 1211.
