Murder of Stephen Hagiochristophorites

Date: September 11, 1185 • Location: Istanbul, Turkey

This milestone marked the outbreak and beginning of this historic period, which spanned 1185–1186.

Isaac II Angelos kills Stephen Hagiochristophorites and then appeals to the people, resulting in the revolt that deposes Andronikos I Komnenos and places Isaac on the throne of the Byzantine Empire.

Isaac II Komnenos Angelos or Angelus was Byzantine Emperor from 1185 to 1195, and co-Emperor with his son Alexios IV Angelos from 1203 to 1204. In an 1185 revolt against the Emperor Andronikos Komnenos, Isaac seized power and rose to the Byzantine throne, establishing the Angelos family as the new imperial dynasty.
