The Federal Republic of Nigeria /naɪˈdʒɪəriə/ (About this sound listen), commonly referred to as Nigeria, is a federal republic in West Africa, bordering Benin in the west, Chad and Cameroon in the east, and Niger in the north. Its coast in the south lies on the Gulf of Guinea in the Atlantic Ocean. It comprises 36 states and the Federal Capital Territory, where the capital, Abuja is located. Nigeria is officially a democratic secular country.
Nigeria has been home to a number of kingdoms and tribal states over the millennia. The modern state originated from British colonial rule beginning in the 19th century, and took its present territorial shape with the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures whilst practising indirect rule through traditional chiefdoms. Nigeria became a formally independent federation in 1960. It experienced a civil war from 1967 to 1970. It thereafter alternated between democratically elected civilian governments and military dictatorships until 1999, with the 2011 presidential election considered the first to be reasonably free and fair.
Nigeria is often referred to as the "Giant of Africa", owing to its large population and economy. With approximately 186 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. Being the most populous country with high fertility rate, Nigeria has the third-largest youth population in the world, after India and China, with more than 90 million children under age 18. The country is viewed as a multinational state as it is inhabited by over 500 ethnic groups, of which the three largest are the Hausa, Igbo and Yoruba; these ethnic groups speak over 500 different languages and are identified with a wide variety of cultures. The official language is English. Nigeria is divided roughly in half between Christians, who live mostly in the southern part of the country, and Muslims, who live mostly in the north. A minority of the population practice religions indigenous to Nigeria, such as those native to the Igbo and Yoruba ethnicities.
