Document 3: States of Nigeria: Date Events Map 1960 - 1963 At the time of independence in 1960, Nigeria was a Federal State of three Regions: Northern, Western, and Eastern. Additionally, provinces, which were a legacy of colonial times, remained extant until they were abolished in 1976. 1963 - 1967 In 1963, two provinces were detached from the Western Region to form the new Mid-Western Region. 1967 - 1976 In 1967, the regions were replaced by 12 states due to a military decree; only the former Mid-Western Region escaped division, and formed a single state following the restructuring. From 1967 to 1970 the areas of Mid-Western State and the Eastern Region attempted to secede, as a nation called Biafra during the Nigerian civil war. 1976 - 1987 In 1976, seven new states were created, making 19 altogether. 1987 - 1991 During this period, there were 21 states and later, Abuja, the Federal Capital Territory. 1991 - 1996 During this period, there were 30 states and the Federal Capital Territory.

Document 14: Nigeria: Modern-day Nigeria has been the site of numerous kingdoms and tribal states over the millennia. The modern state originated from British colonial rule beginning in the 19th century, and 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, and plunged into a civil war from 1967 to 1970. It has since alternated between democratically-elected civilian governments and military dictatorships, until it achieved a stable democracy in 1999, with its 2011 presidential elections being viewed as the first to be conducted reasonably freely and fairly.
