Isaac Comnenus
Isaac Comnenus (d. 1061), son of Manuel Comnenus, a celebrated general, was the first Byzantine Emperor of that dynasty. Left fatherless at an early age, he and his brother John were well educated under the care of Basil II., and advanced to high honour. The soldiers, disgusted at the effeminacy of Basil, soon elected Isaac emperor. He abdicated after a two years' reigr. owing to the decline of his health, and was sue ceeded by Constantine Ducas, his brother John refusing the honour. He died in a monastery.
