The death of Andronikos ended the century-long revival of the Komnenoi, and the Empire descended into civil war as the aristocracy and military elite grappled for control. This led to military weakness, allowing the Turks to regain much of their territory in Anatolia. Within two centuries Constantinople would, for the first time in its thousand-year history as capital of the Byzantine Empire, be conquered by a foreign power. The decline of the Empire began almost immediately, for without the strong Komnenoi emperors, the previous financial and military problems of the Empire became clear and unstoppable.
