10. Nigerian Civil War (1967-1970)
The Nigerian Civil War, also known as the Biafran War, erupted when the southeastern region of Biafra declared independence from Nigeria. The conflict unleashed a catastrophic humanitarian crisis, with widespread famine and suffering capturing global attention.
Nigeria’s eventual reunification was achieved at great cost, forging a new sense of national unity while exposing deep ethnic and regional tensions. The war’s impact still resonates in Nigerian society and has influenced the course of West African politics ever since.
