Their regimes were characterized by financial mismanagement and personal extravagance that reduced Egypt to bankruptcy. These developments led to rapid expansion of British and French financial oversight. This produced popular resentment, which, in 1879, led to revolt. In 1882, British expeditionary forces crushed this revolt, marking the beginning of British occupation and the virtual inclusion of Egypt within the British Empire. During the rule of three successive British High Commissioners between 1883 and 1914, the British agency was the real source of authority. It established special courts to enforce foreign laws for foreigners residing in the country. These privileges for foreigners generated increasing Egyptian resentment. To secure its interests during World War I, Britain declared a formal protectorate over Egypt on December 18, 1914. This lasted until 1922, when, in deference to growing nationalism, the U.K. unilaterally declared Egyptian independence. British influence, however, continued to dominate Egypt's political life and fostered fiscal, administrative, and governmental reforms.
