During World War One, many Arab groups support the Allied powers’ military campaign against the Ottoman Empire. At the end of World War I, the Ottoman Empire collapsed, and the Allied Powers met together to decide what would happen to the territory formerly under Ottoman control. Despite supporting the Allies during the war, many Arab countries were not granted their freedom by the Allies. Still eager to gain Independence, Arabs living in occupied countries began to form ideas about what a free Arab state would look like. These ideas would eventually become the backbone of Pan Arabism.
