Карло I Токко
Ioannina became a center of Greek resistance to the Albanian clans. The Greeks of Ioannina offered power to three foreign rulers during this time, beginning with Thomas II Preljubović (1367–1384), followed by Esau de' Buondelmonti (1385–1411), and finally Carlo I Tocco (1411–1429). The latter finally succeeded in ending the rule of the Albanian clans and unifying Epirus under his rule. Nevertheless, internal dissension eased the Ottoman conquest, which began with the capture of Ioannina in 1430 and continued with Arta in 1449, Angelokastro in 1460, Riniasa Castle and its environs (in what is now Preveza) in 1463, and finally Vonitsa in 1479. With the exception of several coastal Venetian possessions, this was also the end of Latin rule in mainland Greece.
