Constantinople (modern Istanbul)

Constantinople, now Istanbul, was the capital of the Byzantine Empire and is known for its rich history and strategic location between Europe and Asia. Founded by Roman Emperor Constantine the Great in 330 AD, it became a hub for trade, culture, and religion. The city was famous for its impressive architecture, including the Hagia Sophia, and played a crucial role in the spread of Christianity. In 1453, it was conquered by the Ottoman Empire, marking the end of the Byzantine Empire and the beginning of a new era. Istanbul remains a vibrant city, blending Eastern and Western influences.
