Radical secular nationalists replaced failed precursors after 1945. [causal]
During the post–World War II era, a new generation of radical anti-colonial secular nationalists took the place of their predecessors. The previous generation had failed to end colonization, and colonial conditions had become unbearable for the vast majority. Even though by 1945 many Middle Eastern and North African countries had been granted formal independence, in reality they were not free. The League of Arab States, formed in 1945, consisted of the supposedly independent countries of Egypt, Syria, Iraq, Yemen, Lebanon, Transjordan, and Saudi Arabia, but all of these countries were in fact under the thumb of the British. … The loss of Palestine in 1948, and the failure of the Arab states to stop the formation of the state of Israel, exacerbated matters. The result was that popular discontent, combined with leftward pressure exerted by various Communist parties in the region, pushed the nationalist movements in a more radical direction.
XREF: Connects to broader decolonization and Cold War historiography; the Arab League states' nominal independence contrasts with later anti-colonial movements.
