Independence Day (Niger)
The date of the formal, complete independence from France was 3 August 1960, while 18 December 1958 marks the founding of the Republic and creation of the Presidency of the Republic of Niger, following the constitutional changes of the French Fifth Republic, and the elections of 4 December 1958 held across The French Colonial possessions. Nigeriens consider that date to be the founding of their national institutions. Between 18 December 1958 and 3 August 1960, Niger remained a semi-autonomous Republic within the French Community. At the beginning of 1960 a revision of the French Community allowed membership of independent states, and on 28 July the Nigerien Legislative Assembly became the Nigerien National Assembly: Independence was declared on 3 August 1960.
National Day (Cameroon)
National Day is a holiday in Cameroon celebrated on 20 May. On the 20th of May 1972, in a national referendum 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.
