 Over the course of the 12th century, the Palaiologoi were mostly part of the military aristocracy, not recorded as occupying any administrative political offices, and they frequently intermarried with the then ruling Komnenos family, increasing their prestige.When Constantinople fell to the Fourth Crusade in 1204, the Palaiologoi fled to the Empire of Nicaea, a Byzantine successor state ruled by the Laskaris family, where they continued to play an active role and occupied many offices of high rank.In 1259, Michael VIII Palaiologos became co-emperor to the young John IV Laskaris through a coup and in 1261, following the recapture of Constantinople from the Latin Empire, John IV was deposed and blinded.
