 Tagmata would henceforth take on yet a third meaning as a generic term for a standing military unit of regimental size or larger.This tagmatic army, which includes those of the Komnenian and Palaiologan dynasties, would serve the empire in its final stages from the late 11th to the mid-15th centuries, a period longer than the entire lifespans of many other empires.The tagmatic armies would also prove resilient and flexible, even surviving the near destruction of the empire in the aftermath of the fall of Constantinople to the Fourth Crusade in 1204.
