Why did the Arabs fight against the ottoman empire during world war 1?

The Arabs fought against the Ottoman Empire during World War I primarily due to a desire for independence and self-determination. The Ottomans, who were predominantly Turkish, had imposed centralized control over Arab territories, leading to discontent among Arab nationalists. Additionally, the British promised support for Arab independence in exchange for their revolt against the Ottomans, as outlined in the McMahon-Hussein Correspondence. This alliance fueled the Arab revolt, culminating in efforts to establish an independent Arab state.
