How did political boundaries in SW Asia change after World War 1?

After World War I, the political boundaries in Southwest Asia underwent significant changes due to the collapse of the Ottoman Empire. The Treaty of Sèvres in 1920 and later the Treaty of Lausanne in 1923 led to the division of Ottoman territories among European powers, resulting in the establishment of new nation-states such as Iraq, Syria, Lebanon, and Jordan. This redrawing of borders often disregarded ethnic and sectarian divisions, sowing the seeds for future conflicts in the region. The influence of Western powers in shaping these boundaries had lasting implications for regional politics and stability.
