 The final, fatal blow to the thematic army occurred in the aftermath of the disaster at the Battle of Manzikert in 1071, when a new enemy, the Seljuk Turks, overran most of Asia Minor along with most the empire's themes.Once again, the empire was forced to adapt to a new strategic reality with reduced borders and resources.Under Emperor Alexios I Komnenos the themes were done away with and the military restructured around the tagmata, some of which were stationed in the provinces, but the majority usually remained near Constantinople when not on campaign.
