At the onset of the reign of Alexios I, the empire was reeling from its defeat by the Seljuk Turks at the Battle of Manzikert in 1071. The empire was also being threatened by the Normans of Robert Guiscard, who were invading the Balkans from their base in southern Italy. All this occurred as the empire's military institution was in disarray and had grown increasingly reliant on mercenaries. Previous emperors had also squandered the large gold deposits of Constantinople, so the defense of the empire had broken down, and there were few troops to fill the gaps.  - Manuel I Komnenos (or Comnenus "Manoul I Komnnos"; 28 November 1118  24 September 1180) was a Byzantine Emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire had seen a resurgence of its military and economic power, and had enjoyed a cultural revival.
