The Ottoman Empire was dissolved after their loss in which war?

The Ottoman Empire was dissolved after their loss in World War I primarily due to a combination of military defeats, internal unrest, and external pressures from other powers. The empire aligned itself with the Central Powers during the war, but suffered significant losses on multiple fronts, including in the Caucasus, Mesopotamia, and the Arabian Peninsula. The empire's infrastructure was severely impacted, its economy weakened, and its military strength reduced. Additionally, the empire faced internal rebellions from various ethnic and nationalist groups seeking independence, such as the Arabs and the Armenians. The external pressures and post-war negotiations, including the Treaty of Sèvres, led to the dismantling of the Ottoman Empire, the establishment of new nation-states in its territories, and the modernization of Turkey under Mustafa Kemal Atatürk's leadership.
