The Nigerian Civil War, also known as the Biafra War, which occurred from May 27, 1967, to January 12, 1970, stands as a pivotal event in African military history and diplomatic relations. It marked the collision of 20th-century technology on the battlefield where Nigerians engaged in conventional combat amidst diplomatic maneuvering, military ideology, and propaganda. This conflict was deeply rooted in Nigeria’s historical political issues, characterized by ethnic, religious, and regional divisions. The Biafran diplomatic campaign sought international recognition, crucial for garnering support from global powers like the United States and France. The war, stemming from ethnic tensions and political unrest, saw the emergence of Biafra seeking independence from Nigeria, leading to a bitter and bloody conflict ultimately ending in Biafra’s defeat. This study aims to examine the ideological impact of the Biafra War on Nigeria, focusing on diplomatic strategies employed, political shifts, and international involvement. Through a comprehensive analysis of primary and secondary sources, including government publications, interviews, and archival materials, this research seeks to fill gaps in understanding the complexities of the Nigerian Civil War and its enduring ramifications on the nation’s politics and diplomatic relations.
