Medieval Greece

Greece's medieval history is dominated by the Byzantine Empire which revolved around Christianity, Greek Language and Civilization, and Roman law. It was a powerful force in the Mediterranean basin for centuries, engaging in trade, politics, and the spread of Christianity. The empire collaborated with Rome during the Crusades against the Muslims. However, during the 13th century, the Crusaders turned on the Byzantine Empire itself and sacked Constantinople. With a weakened Byzantine Empire, Frankish and Latin invaders arrived and occupied various parts of Greece. Over the following centuries, the Byzantine Empire began to regain strength and reconquer lost territory, but received a final blow in the 15th century when a growing Ottoman Turkish Empire to the east conquered Constantinople.
