Why did turkey have 2 treaties?

Turkey had two treaties primarily due to the aftermath of World War I and the collapse of the Ottoman Empire. The Treaty of Sèvres in 1920 aimed to partition the empire but faced strong opposition from Turkish nationalists, leading to the War of Independence. This conflict resulted in the Treaty of Lausanne in 1923, which recognized the sovereignty of the new Republic of Turkey and established its modern borders, superseding the earlier treaty.
