'''Isaac II Angelos''' or '''Angelus''' ({{langx|el|Ἰσαάκιος Κομνηνός Ἄγγελος|Isaákios Komnēnós Ángelos}}; September 1156&nbsp;– 28 January 1204) was [[Byzantine Emperor]] from 1185 to 1195, and co-Emperor with his son [[Alexios IV Angelos]] from 1203 to 1204. In a 1185 revolt against the Emperor [[Andronikos I Komnenos|Andronikos Komnenos]], Isaac seized power and rose to the Byzantine throne, establishing the [[Angelos]] family as the new imperial dynasty. 

His father [[Andronikos Doukas Angelos]] was a military leader in [[Asia Minor]] (c. 1122&nbsp;– aft. 1185) who married [[Euphrosyne Kastamonitissa]] (c. 1125&nbsp;– aft. 1195). Andronikos Doukas Angelos was the son of Constantine Angelos and [[Theodora Komnene (daughter of Alexios I)|Theodora Komnene]] (b. 15 January 1096/1097), the youngest daughter of Emperor [[Alexios I Komnenos]] and [[Irene Doukaina]]. Thus Isaac was a member of the extended imperial clan of the [[Komnenoi]].
