Eastern Region, Nigeria in the context of "Ijaw people"

The Nigerian Civil War (6 July 1967 – 15 January 1970), also known as the Biafran War, Nigeria-Biafra War, or Biafra War, was an armed conflict fought between Nigeria and the Republic of Biafra, a secessionist state which had declared its independence from Nigeria in 1967. During the war years, Field Marshal Gowon served as the head of state of Nigeria, while Biafra was led by Lieutenant Colonel Chukwuemeka "Emeka" Odumegwu Ojukwu. The conflict emerged from political, ethnic, cultural, and religious tensions that preceded the United Kingdom's formal decolonisation of Nigeria from 1960 to 1963. Immediate causes of the war in 1966 included a military coup, a counter-coup, and anti-Igbo pogroms in the Northern Region. As a consequence of these pogroms, alongside the mass exodus of surviving Igbos from the Northern Region to the Igbo homelands in the Eastern Region, the leadership of the Eastern Region concluded that the Nigerian federal government was either unwilling or unable to guarantee them an adequate protection, therefore, the only remaining solution seemed to be to secure their compatriots' security by establishing a sovereign and independent country of Biafra.

Within a year, Nigerian government troops surrounded Biafra, while capturing coastal oil facilities and the city of Port Harcourt. In the aftermath of the Nigerian military's encirclement of the major part of Biafra, a blockade was imposed as a deliberate policy during the ensuing stalemate, which led to the mass starvation of Biafran civilians. During the 2+1⁄2 years of the war, there were approximately 100,000 overall military casualties, while between 500,000 and 2 million Biafran civilians died of starvation.

Biafra (/biˈæfrə/ bee-AF-rə; from Igbo: Bìá fá rá), officially the Republic of Biafra, was a partially recognised state in West Africa that declared independence from Nigeria and existed from 1967 to 1970. Its territory consisted of the former Eastern Region of Nigeria, predominantly inhabited by the Igbo ethnic group. Biafra was established on 30 May 1967 by Igbo military officer and Eastern Region governor Chukwuemeka Odumegwu Ojukwu under his presidency, following a series of ethnic tensions and military coups after Nigerian independence in 1960 that culminated in the 1966 anti-Igbo pogrom.

The Nigerian military attempted to reclaim the territory of Biafra, resulting in the beginning of the Nigerian Civil War. Biafra was officially recognized as a sovereign and independent country by Gabon, Haiti, Côte d'Ivoire, Tanzania, and Zambia while receiving de facto recognition and covert military support from France, Portugal, Israel, South Africa, and Rhodesia. After nearly three years of war, during which around two million Biafran civilians died, president Ojukwu fled into exile in the Ivory Coast as the Nigerian military approached the capital of Biafra. Philip Effiong became the second president of Biafra, overseeing the surrender of Biafran forces to Nigeria.

Chukwuemeka Odumegwu Ojukwulisten (4 November 1933 – 26 November 2011) was a Nigerian military officer and political figure who served as President of Biafra from 1967 to 1970. As the military governor of the Eastern Region of Nigeria, which he declared as the independent state of Biafra, Ojukwu led the Biafran forces during the Nigerian Civil War against the Nigerian government forces.

Born in Zungeru, British Nigeria to Louis Odumegwu Ojukwu, a wealthy Igbo businessman, Ojukwu was educated at King's College, Lagos and Epsom College in Surrey, England. He proceeded to Lincoln College, Oxford University where he obtained a master's degree in Modern History in 1955. He returned to Nigeria to serve as an administrative officer and would later join the Nigerian army. Following the independence of Nigeria in 1960, a group of military officers overthrew Nigeria's civilian government in the 1966 Nigerian coup d'état and Johnson Aguiyi-Ironsi became the head of state. Ironsi appointed Ojukwu as military governor of the Eastern Region mostly dominated by the Igbo tribe.

The 1966 anti-Igbo pogroms were a series of widespread massacres and pogroms committed against Igbo people–and other people of southern Nigerian origin–living in northern Nigeria, starting in May 1966 and reaching its peak after 29 September 1966. Between 8,000 and 30,000 Igbos and easterners have been estimated to have been killed. A further 1 million Igbos fled the Northern Region into the East. In response to the killings, some northerners were massacred in Port Harcourt and other cities in eastern Nigeria. These events led to the secession of the eastern Nigerian region and the declaration of Biafra, which ultimately led to the Nigerian Civil War.
