By the 1920 Treaty of Sèvres Anatolian Turkey was to be partitioned, with the areas north of the Mosul Vilayet to be included within an autonomous or independent Kurdish state.[1][17] Turkish nationalists were outraged at the treaty, contributing to the outbreak the Turkish War of Independence; the Turkish success in this conflict rendered Sèvres obsolete.[9] By the 1923 Treaty of Lausanne Turkey's independence was recognised and a far more generous territorial settlement was agreed upon, albeit at the cost of Turkey formally renouncing any claim to Arab lands.[18] In the east the former Ottoman-Iran boundary was retained, now forming the borders between Iran and Iraq, and also Iran and the new Republic of Turkey.[9]
