The Komnenian restoration refers to a period in the Byzantine Empire during the 11th and 12th centuries, marked by the reign of the Komnenos dynasty. This era began with the ascension of Alexios I Komnenos in 1081, who sought to stabilize the empire after years of decline and external threats, particularly from the Seljuk Turks and the Normans. Under the Komnenian rulers, the Byzantine Empire experienced military, economic, and administrative reforms. These changes helped to restore the empire's power and influence, leading to a resurgence in trade and culture. The period is also notable for the beginning of the Crusades, which further impacted Byzantine relations with Western Europe.
