Independence Day of Nigeria

Nigeria was granted independence on October 1, 1960. A new constitution established a federal system with an elected prime minister and a ceremonial head of state.
Although Nigeria gained partial independence from Britain on October 1 1960, it was not totally independent until 1963 when the Declaration of Independence was signed and became a republic.

Nigeria is often referred to as the "Giant of Africa", due to its large population and economy. With approximately 174 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. The country is inhabited by over 500 ethnic groups, of which the three largest are the Hausa, Igbo and Yoruba.
The name “Nigeria” is derived from the word “Niger” – the name of the river that constitutes the most remarkable geographical feature of the country.

History
