National Day is a holiday in Cameroon celebarated on 20 May. Cameroon has no single date of independence. 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 PresidentAhmadou Ahidjo's abolishment of the federal system of government and creation of a unitary COUNTRY in 1972.
