Macedonian dynasty
The Komnenian era was born out of a period of great difficulty and strife for the Byzantine Empire. Following a period of relative success and expansion under the Macedonian dynasty (c. 867–c. 1054), Byzantium experienced several decades of stagnation and decline, which culminated in a vast deterioration in the military, territorial, economic and political situation of the Byzantine Empire by the accession of Alexios I Komnenos in 1081.
