In 1900, the territories under the control of the Royal Niger Company became the Southern Nigeria Protectorate. In 1914, this was combined with the Northern Nigeria Protectorate to create the Colony and Protectorate of Nigeria, which forms the borders of modern day Nigeria.

Many aspects of modern life in Nigeria were established under the period of British Rule, but by the middle of the 20th century, the call for independence sweeping across Africa and the decline of the territories in the British Empire led to Nigeria being granted independence on 1 October 1960 under a constitution with a parliamentary government and a degree of autonomy for the country's three regions.

Nigeria marked total independence from Britain when it became a federal republic when a new constitution was adopted on 1 October 1963 with Nnamdi Azikiwe as its first president.

Political unrest led to a series of military coups in 1966 and Nigeria was ruled by a military junta with democratic rule not being restored until 1 October 1979.
