Final answer:
Arab nationalist movements post-1945 saw the emergence of secular, militaristic governance, influenced by Nasserism, Arab unity aspirations, and Cold War dynamics.
Step-by-step explanation:
After 1945, patterns in Arab nationalist movements began to surface as reactions to geopolitical pressures, post-colonial aspirations, and local governance frustrations. Gamal Abdel Nasser became a symbol of this shift, pursuing a secular, pan-Arab government while leading the Free Officers Movement's overthrow of the Egyptian monarchy in 1952. Nasserism advocated for a secular state, economic reform to curb foreign control, and improved social services, establishing a model followed by other Arab leaders and influencing movements like the Ba'ath Party in Syria and Iraq.
The emphasis on military strength to maintain order was also a recurring theme, as seen in the Mamluk dynasty's historical rise through military might. During the Cold War, the Arab-Israeli conflict and global superpower dynamics further shaped Arab nationalism, fueling the desire for unity among Arab states and laying the groundwork for moments of unity such as the union between Egypt and Syria in the 1960s and other federations in the 1970s.
