Shortly after Mozambique's 1975 independence from Portugal, the RENAMO insurgency, initially organized by Rhodesian intelligence and later sponsored by apartheid South Africa as a proxy against the Marxist FRELIMO government, launched a brutal guerrilla war marked by attacks on civilians, infrastructure, and rural health and education systems. The war, compounded by drought and famine, killed an estimated 1 million people and displaced roughly 5 million, including about 1.7 million who became refugees in neighboring Malawi, Zimbabwe, South Africa, Tanzania, Eswatini (then Swaziland) and Zambia. A 1992 peace accord ended the war and led to Mozambique's first multiparty elections in 1994, though most refugees and IDPs had returned by the mid-1990s.

Mozambique's 1980 census counted 11,673,725 people. UNHCR registered about 1.7 million Mozambican refugees in neighbouring countries by 1992, chiefly in Malawi, Zimbabwe and South Africa, alongside an estimated 3-4 million internally displaced — the largest refugee operation in Africa at the time.
The commonly cited figure of about 1 million war-related deaths is an excess-mortality estimate dominated by famine and the collapse of health and food systems rather than a count of killings; UNICEF attributed several hundred thousand of these to child deaths from war-induced deprivation. The US State Department's Gersony Report (1988), based on refugee interviews, attributed about 100,000 deaths specifically to RENAMO violence — a figure RENAMO's US supporters, including the Heritage Foundation, publicly contested as methodologically unsound. The low end reflects more conservative demographic reconstructions.
The Gersony Report for the US State Department, based on extensive refugee interviews, documented RENAMO's systematic murder of civilians, abduction of children and adults for forced portering and combat, and destruction of villages, transport, health posts and food stocks that produced mass starvation.
