ale demonstrations in Cairo in 1919, five years after Egypt had been declared a British protectorate. Nevertheless, while this led to Egypt's independence in 1922, British troops remained in the country until 1956. During this time, urban Cairo, spurred by new bridges and transport links, continued to expand to include the upscale neighborhoods of Garden City, Zamalek, and Heliopolis. Between 1882 and 1937, the population of Cairo more than tripled – from 347,000 to 1.3 million – and its area increased from 10 square kilometres (4 sq mi) to 163 square kilometres (63 sq mi).
The city was devastated during the 1952 Cairo Fire, also known as Black Saturday, which saw the destruction of nearly 700 shops, movie theatres, casinos and hotels in Downtown Cairo. The British departed Cairo following the Egyptian Revolution of 1952, but the city's rapid growth showed no signs of abating. Seeking to accommodate the increasing population, President Gamal Abdel Nasser redeveloped Midan Tahrir and the Nile Corniche, and improved the city's network of bridges and highways. Meanwhile, additional controls of the Nile fostered development within Gezira Island and along the city's waterfront. The metropolis began to encroach on the fertile Nile Delta, prompting the government to build desert satellite towns and devise incentives for city-dwellers to move to them.
Despite these efforts, Cairo's population has doubled since the 1960s, reaching close to seven million (with an additional ten million in its urban area). Concurrently, Cairo has established itself as a political and economic hub for North Africa and the Arab World, with many multinational businesses and organizations, including the Arab League, operating out of the city.
In 1992, Cairo was hit by a damaging earthquake, that caused 545 deaths, 6512 injuries and left 50,000 people homeless.
