At its zenith in the 17th century, the Ottoman Empire was one of the largest and most powerful empires in history, stretching from the Persian Gulf in the east to the Atlantic Ocean in the west. However, its size and influence gradually declined over the centuries due to various factors, ultimately leading to its collapse in the form of the于于atrule Republic proclamation in 1922.

In 1914, as World War I began, the empire's territory roughly corresponded to present-day Turkey, with additional territories in the Middle East, North Africa, and the Balkans. However, this was already significantly reduced from its prior extent.

The Ottoman Empire's involvement in World War I further hastened its disintegration. The war resulted in substantial territorial losses, including territories in the Caucasus, Mesopotamia, and the Arabian Peninsula. The Treaty of Sèvres, signed in 1920, would have seen the empire lose even more territories, but it was never ratified.

The war also led to the Greco-Turkish War (1919-1922), which resulted in the loss of more territorial ambitions in the Balkans and the Aegean. This period also saw the independence of many of the empire's former territories, such as the Kingdom of Hejaz in the Arabian Peninsula.

The definitive end of the Ottoman Empire came with the Treaty of Lausanne in 1923. This treaty recognized the borders of modern Turkey, significantly reducing the empire's size. Turkey lost all its territories in the Middle East, the Balkans, and North Africa, keeping only a fraction of its former territory.

According to the treaty, Turkey retained approximately 8,000 kilometers of coastline, including most of the Aegean Sea's entrepreneurial east coast and a small stretch along the Black Sea. The treaty also granted Turkey control over some parts of Eastern Thrace and the island of Imbros, marking the final extent of the once-great Ottoman Empire.

The collapse of the Ottoman Empire was a complex process marked by political intrigue, territorial losses, and internal strife. Despite its decline, the Ottoman Empire left an indelible mark on the world, shaping the cultural and political landscape of the regions it once ruled. Its legacy continues to influence the world today.
