Byzantine Empire was the eastern part of the Roman Empire after the west fell in 476 CE. Its capital city was Constantinople, located between Europe and Asia. The empire lasted from about 330 CE to 1453 CE.

Greek became the main language instead of Latin. The empire is known for large churches such as Hagia Sophia, with its massive dome and detailed mosaics. Christianity played a central role in daily life and government.

Constantinople was an important center of trade and culture for centuries. The empire ended when the city was captured in 1453.
