Constantine Angelos

[4] Despite his lowly (outside the close imperial circle) origin, Constantine was reportedly brave and exceedingly beautiful,[2] and managed to win the heart of Theodora Komnene (born 1097), the fourth daughter of Emperor Alexios I Komnenos (r. 1081–1118) and Irene Doukaina.

[9] Thus on 26 February 1147 he participated in the church council of Blachernae that deposed Patriarch Cosmas II Attikos, being ranked in fourth place behind the heir-apparent, despotes Bela-Alexios, the Caesar John Rogerios Dalassenos, and the panhypersebastos Stephen Kontostephanos.

[13][10][14] In 1154, as Manuel prepared for war with William I of Sicily, he gave his uncle command of the Byzantine fleet and ordered him to proceed to Monemvasia, where to await further reinforcements.

His brother Nicholas managed to escape with a handful of ships, but Constantine was captured and princely imprisoned in Palermo for few years until 1158, when Manuel concluded a peace treaty with William.

[2][3] Beginning with Du Cange, many earlier historians distinguished between two persons of this name, since the sources record that a minor noble named Constantine Angelos, from Philadelphia, married the fourth daughter of Alexios I Komnenos and received the title of pansebastohypertatos, whereas the Constantine Angelos, uncle of Manuel I and active during the latter's reign, is recorded in the sources as a sebastohypertatos.
