 and the flight of Alexios III from the capital. But both mind and body had been enfeebled by confinement, and his son Alexios IV Angelos was associated on the throne as the effective monarch.

Heavily beholden to the crusaders, Alexios IV was unable to meet his obligations and his vacillation caused him to lose the support of both his crusader allies and his subjects. At the end of January, 1204, the influential court official Alexios Doukas Mourtzouphlos took advantage of riots in the capital to imprison Alexios IV and seize the throne as Emperor Alexios V. At this point Isaac II died, allegedly of shock, while Alexios IV was strangled on January 28 or 29.

Historical reputation

Isaac has the reputation of one of the most unsuccessful princes that occupied the Byzantine throne.
