Independence

The Federation of Nigeria was granted full independence on 1 October 1960 under a constitution that provided for a parliamentary government and a substantial measure of self-government for the country's three regions. From 1959 to 1960, Jaja Wachuku was the First Nigerian Speaker of the Nigerian Parliament, also called the "House of Representatives." Jaja Wachuku replaced Sir Frederick Metcalfe of Britain. Notably, as First Speaker of the House, Jaja Wachuku received Nigeria's Instrument of Independence, also known as Freedom Charter, on 1 October 1960, from Princess Alexandra of Kent, The Queen's representative at the Nigerian independence ceremonies.

The Federal government was given exclusive powers in defense, foreign relations, and commercial and fiscal policy. The monarch of Nigeria was still head of state but legislative power was vested in a bicameral parliament, executive power in a prime minister and cabinet, and judicial authority in a Federal Supreme Court. Political parties, however, tended to reflect the make up of the three main ethnic groups. The Nigerian People's Congress (NPC) represented conservative, Muslim, largely Hausa and Fulani interests that dominated the Northern Region. The northern region of the country, consisting of three-quarters of the land area and more than half the population of Nigeria.[26] Thus the North dominated the federation government from the beginning of independence. In the 1959 elections held in preparation for independence, the NPC captured 134 seats in the 312-seat parliament.
