Following the Fourth Crusade and the fall of Constantinople to the "Latins" in 1204, mainland Greece was split between the Greek Despotate of Epirus (a Byzantine successor state) and French rule (known as the ''Frankokratia''), while some islands came under Venetian rule. The re-establishment of the Byzantine imperial capital in Constantinople in 1261 was accompanied by the empire's recovery of much of the Greek peninsula, although the Frankish Principality of Achaea in the Peloponnese and the rival Greek Despotate of Epirus in the north both remained important regional powers into the 14th century, while the islands remained largely under Genoese and Venetian control. During the Paleologi dynasty (1261–1453) a new era of Greek patriotism emerged accompanied by a turning back to ancient Greece.
