The historical role of the Byzantine Empire in Europe was multifaceted, serving as a bridge between East and West. Emerging from the remnants of the Roman Empire, the Byzantine Empire preserved classical knowledge, art, and traditions, which influenced the Renaissance. It was a center for trade and cultural exchange, and its capital, Constantinople, was pivotal for maintaining communication between Europe and Asia. The empire also played a crucial role in the spread of Christianity and served as a bulwark against Islamic expansion into Europe during its decline.
