Istanbul, formerly known as Byzantium, is a city with a rich history that dates back to ancient times. Founded by Greek colonists around 660 BCE, it served as a significant trading hub due to its strategic location between Europe and Asia. The city was later renamed Constantinople in 330 CE when Emperor Constantine the Great established it as the new capital of the Roman Empire. This transformation marked the beginning of its prominence in both political and cultural spheres.

Throughout its history, Istanbul has been a melting pot of diverse cultures and religions, reflecting influences from the Greeks, Romans, and later the Ottomans, who conquered the city in 1453. The architectural landscape of Istanbul showcases this rich heritage, featuring iconic structures such as the Hagia Sophia and the Topkapi Palace. As a historical center of Christianity and Islam, the city has played a crucial role in the religious and cultural exchanges between Eastern and Western civilizations.

Today, Istanbul stands as a vibrant metropolis that embodies its ancient legacy while continuously evolving. Its layered history remains a point of interest for scholars, tourists, and residents alike, making it a unique destination that honors its multifaceted past.
