The people of Nigeria have an extensive history, and archaeological evidence shows that human habitation of the area dates back to at least 9000 BC.[3] The Benue-Cross River area is thought to be the original homeland of the Bantu migrants who spread across most of central and southern Africa in waves between the 1st millennium BC and the 2nd millennium AD.

On October 1, 1960, Nigeria gained its independence from the United Kingdom, and now consists of 36 states and the federal capital territory. Nigeria re-achieved democracy in 1999 after a sixteen-year interruption; from 1966 until 1999, Nigeria had been ruled (except the short-lived second republic, 1979-1983) by military dictators who seized power in coups d'état and counter-coups during the Nigerian military juntas of 1966-1979 and 1983-199
More than 2,000 years ago the Nok people in central Nigeria produced sculptures that have been discovered by archaeologists.[4] In the northern part of the country, Kano and Katsina has recorded history which dates back to around AD 999. Hausa kingdoms and the Kanem-Bornu Empire prospered as trade posts between North and West Africa.

The Yoruba kingdoms of If? and Oyo in the western block of the country were founded about 700-900 and 1400 respectively. Yoruba mythology believes that Ile-Ife is the source of the human race and that it predates any other civilization. If? produced the terra cotta and bronze heads, the ?y? extended as far as modern Togo. Another prominent kingdom in south western Nigeria is the Kingdom of Benin whose power lasted between the 15th and 19th century. Their dominance reached as far as the well known city of Lagos which is also called "Eko" by the indigenes.

Two slightly differing Okpoho Manillas, an archaic form of Nigerian money.Newly independent Nigeria's government was a coalition of conservative parties: the Nigerian People's Congress (NPC), a party dominated by Northerners and those of the Islamic faith, and the Igbo and Christian dominated National Council of Nigeria and the Cameroons (NCNC) led by Nnamdi Azikiwe, who became Nigeria's maiden Governor-General in 1960. Forming the opposition was the comparatively liberal Action Group (AG), which was largely dominated by Yorubas and led by Obafemi Awolowo.[5] An imbalance was created in the polity by the result of the 1961 plebiscite. Southern Cameroon opted to join the Republic of Cameroon while northern Cameroon chose to remain in Nigeria. The northern part of the country was now far larger than the southern part. The nation parted with its British legacy in 1963 by declaring itself a Federal Republic, with Azikiwe as the first president. When elections came about in 1965, the AG was outmaneuvered for control of Nigeria's Western Region by the Nigerian National Democratic Party, an amalgamation of conservative Yoruba elements backed heavily by the Federal Government amid dubious electoral circumstances. This left the Igbo NCNC to coalesce with the remnants of the AG in a weak progressive alliance.[5]

Map of NigeriaThis disequilibrium and perceived corruption of the electoral and political process led in 1966 to several back-to-back military coups. The first was in January and led by a collection of young leftists under Major Emmanuel Ifeajuna & Chukwuma Kaduna Nzeogwu, it was partially successful - the coupists overthrew the embattled government but could not install their choice, jailed opposition leader Chief Obafemi Awolowo, General Johnson Aguiyi-ironsi, then head of the army was invited by the rump of the Balewa regime to take over the affairs of the country as head of state. This coup was counter-acted by another successful plot, supported primarily by Northern military officers and Northerners who favored the NPC, it was engineered by Northern officers, which allowed Lt Colonel Yakubu Gowon to become head of state. This sequence of events led to an increase in ethnic tension and violence. The Northern coup, which was mostly motivated by ethnic and religious reasons was a bloodbath of both military officers and civilians, especially of Igbo extraction. The violence against Igbos increased their desire for autonomy and protection from the military's wrath. By May 1967, the Eastern Region had declared itself an independent state called the Republic of Biafra under the leadership Lt Colonel Emeka Ojukwu in line with the wishes of the people. The Nigerian side attacked Biafra on July 6, 1967 at Garkem signaling the beginning of the 30 month war that ended on January 1970.[6] Following the war, Nigeria became to an extent even more mired in ethnic strife, as the defeated southeast was now conquered territory for the federal military regime, which changed heads of state twice as army officers staged a bloodless coup against Gowon and enthroned Murtala Mohammed; Olusegun Obansanjo succeeded the former after an assassination. During the oil boom of the 1970s, Nigeria joined OPEC and billions of dollars generated by production in the oil-rich Niger Delta flowed into the coffers of the Nigerian state. However, increasing corruption and graft at all levels of government squandered most of these earnings. As oil revenues fueled the rise of federal subventions to states and precariously to individuals, the Federal Government soon became the center of political struggle and the center became the threshold of power in the country. As oil production and revenue rose, the Nigerian government created a dangerous situation as it became increasingly dependent on oil revenues and the international commodity markets for budgetary and economic concerns eschewing economic stability.[7]

Beginning in 1979, Nigerians participated in a brief return to democracy when Obasanjo transferred power to the civilian regime of Shehu Shagari. The Shagari government was viewed as corrupt and incompetent by virtually all sectors of Nigerian society, so when the regime was overthrown by the military coup of Mohammadu Buhari shortly after the regime's fraudulent re-election in 1984, it was generally viewed as a positive development by most of the population.[8] Buhari promised major reforms but his government proved little better than its predecessor, and his regime was overthrown via yet another military coup in 1985.[9] The new head of state, Ibrahim Babangida, promptly declared himself President and Commander in chief of the Armed Forces and the ruling Supreme Military Council and also set 1990 as the official deadline for a return to democratic governance. Babangida's tenure was marked by a flurry of political activity: he instituted the International Monetary Fund's Structural Adjustment Program (SAP) to aid in the repayment of the country's crushing international debt, which most federal revenue was dedicated to servicing. He also inflamed religious tensions in the nation and particularly the south by enrolling Nigeria in the Organization of the Islamic Conference,[10] he survived an abortive coup and pushed back the promised return to democracy to 1992. When free and fair elections were finally held in 1993, Babangida declared the results showing a presidential victory for M.K.O. Abiola null and void, sparking mass civilian violence in protest which effectively shut the country down for weeks and made Babangida to keep his often shaky promise to leave office to a civilian run government.[11] Babangida's regime is adjudged to be at the apogee of corruption in the history of the nation as it was during his time that corruption became officially diluted in Nigeria.[12]

Olusegun Obasanjo of the People's Democratic Party is the current president of NigeriaBabangida's caretaker regime headed by Ernest Shonekan survived only until late 1993 when General Sani Abacha took power in another military coup. Abacha proved to be perhaps Nigeria's most brutal ruler and employed violence on a wide scale to suppress the continuing pandemic of civilian unrest. Abacha was not only brutal but very corrupt.[13] While Babaginda encouraged his friends, family and himself to steal money, Abacha made corruption a family affair. Money had been found in various western European countries banks traced to him. He avoided coup plots by bribing army generals. Several hundred millions dollars in accounts traced to him were unearthed in 1999.[14] The regime of terror would come to an end in 1998 when the dictator was found dead amid dubious circumstances. Abacha's death finally yielded an opportunity for return to civilian rule and Nigeria elected Olusegun Obasanjo, a Yoruba and former military head of state, as the new president. Although the elections which brought Obasanjo to power in 1999 and again in 2003 were condemned as anything but free and fair, Nigeria has shown marked improvements in attempts to tackle government corruption and to hasten development at all levels. This is despite continuing calls for a Sovereign National Conference to discern the genuine will of the people, which the president has deftly sidestepped for eight years, as well as widespread disputes and ethnic violence over the oil producing land of the Niger Delta. While Obasanjo has shown willingness to fight corruption, he has been accused by others of the same
