Historical Trajectory
Phase I: Rise
The United Arab Republic was proclaimed on 1 February 1958 when Egypt and Syria merged under President Gamal Abdel Nasser, driven by pan-Arab nationalist sentiment and a desire to counter Western influence in the region. The union also incorporated Egyptian-administered Gaza. Shortly after, the UAR joined with the Mutawakkilite Kingdom of Yemen in a loose confederation called the United Arab States.
Phase II: Zenith
At its peak, the UAR encompassed Egypt, Gaza, and Syria, positioning Nasser as the foremost leader of Arab nationalism across the Middle East. Cairo functioned as the political and cultural center, and the republic projected an image of Arab unity that inspired nationalist movements throughout the Arab world, while Nasser pursued a non-aligned foreign policy during the Cold War.
Phase III: Decline
Tensions between Egyptian dominance and Syrian political and military elites eroded the union. In September 1961, a Syrian coup d'état led to Syria's secession from the UAR. Egypt retained the name United Arab Republic for a decade under Nasser and then his successor, until President Anwar Sadat formally dissolved it in September 1971, renaming the country the Arab Republic of Egypt.
