The United Arab Republic, more commonly known as Egypt-Syria, was a political union between Egypt and Syria lasting for 20 years.
Regarded as the first step in forming a Pan-Arabic state, the union was heavily influenced by the Unitarian ideology. It was founded by Egyptian President Abdel Nasser in 1961, who initially tried to secure his own power by removing the popular Ba'ath party from power. Following his death in 1975, the Ba'ath Party came back to power, and formed alliances with other anti-Western Islamic states against the Western-allied nations of the Middle East.
Tensions between the fundamentalist and Western-backed nations resulted in the First Arabian War in 1981. Despite initial "Arab Alliance" success, the entry of the United States and stubborn defense resulted in their defeat. In the Treaty of Venice, Egypt-Syria was forcibly dismantled and separated back into two states. This Western victory set off a wave of anti-Western fundamentalism in the Middle East. Following the war, neither Egypt nor Syria would recover from the blow, being replaced by Iraq as the major fundamentalist force in the Middle East.
