The National Day (French: Fête Nationale) of Cameroon, also known as Unitary State Day (fête nationale de l'État unitaire), is celebrated annually on 20 May.^[1][2] In a national referendum on 20 May 1972, Cameroonians voted for a unitary state as opposed to the existing federal state. The United Nations Trust Territory known as French Cameroun achieved independence from France on 1 January 1960, and British Southern Cameroons changed status from a Trusteeship under British administration to a federated state within Cameroon on 1 October 1961. The government chose 20 May as Cameroon's National Day to commemorate President Ahmadou Ahidjo's abolishment of the federal system of government in favor of a unitary country in 1972.^[3]
