Euphrosyne Doukaina Kamatera,
empress (1195–1203); fl. ca.1169–1210.
She married the future Alexios III Angelos ca.1169 and bore him three daughters: Irene (born ca.1170), Anna (born ca.1171 or 1173), and Eudokia (born ca.1172 or 1174). Stronger-willed and more intelligent than Alexios, she had great influence over him; she occupied the palace when word of his coup reached Constantinople. Her support for Constantine Mesopotamites created opposition from her son-in-law Andronikos Kontostephanos and her brother Basil Kamateros, who informed Alexios of her affair with a certain Vatatzes. The latter was executed and Euphrosyne was shut in a convent for six months (1196–97). Upon her return she regained dominance over her husband, although she could not prevent Mesopotamites' fall (1197). Abandoned by Alexios in Constantinople when he fled, she was arrested, but Alexios V Doukas took Euphrosyne and Eudokia with him when he left Constantinople. After Alexios V and Alexios III met at Mosynopolis, Euphrosyne joined her husband in his wanderings. Carried off to Montferrat with him, she was ransomed by Michael I Komnenos Doukas of Epiros and passed the rest of her life near Arta.
