In January 1952, British forces attacked a police station leaving around 50 people dead. The capital of Egypt, Cairo, overflowed with British anti-violence in a riot on 26 January 1952 known as the "Black Saturday" riot. The Black Saturday riots led to the development of the Free Officer movement, consisting of a thousand "middle-level" officers, overthrowing King Farouk. After the Egyptian Revolution of 1952 that overthrew the monarchy and established a republic, Gamal Abdel Nasser rose to power on themes that mixed Arab and Egyptian nationalism. Nasser saw Egypt as the leader of the Arab states and saw Egypt's role as promoting Arab solidarity against both the West and Israel. Nasser's first priority was end subordination to Britain which meant most urgently the removal of British bases privileges and acquire greater control over the Suez Canal.
