In 3–5 sentences, analyze a pattern that emerged in Arab nationalist movements after 1945.

After 1945, a pattern emerged in Arab nationalist movements of trying to unite Arab countries under a common identity in opposition to colonial powers. This was seen in the formation of the Arab League in 1945, which sought to promote economic and cultural cooperation among Arab states. Additionally, Arab nationalist movements often focused on the idea of pan-Arabism, or the belief in a unified Arab state encompassing all Arab-speaking countries. However, this vision was often undermined by divisions, rivalries, and power struggles among Arab leaders and nations. Ultimately, the pattern of Arab nationalist movements after 1945 reflected a desire for unity and independence, but was hindered by internal and external challenges.
