The 1966 Coup That Overthrew Ghana's Kwame Nkrumah

On February 24, 1966, while President Kwame Nkrumah was traveling to Hanoi on a self-styled peace mission concerning the Vietnam War, army and police officers in Accra seized key installations across Ghana and announced they had removed him from power. The operation, later given the codename Operation Cold Chop, was led by Colonel Emmanuel Kwasi Kotoka, Major Akwasi Afrifa, and police officers including John Willie Harlley, and it met little organized resistance. Within hours the plotters controlled the radio station, government buildings, and the capital itself, and they announced the formation of an eight-member National Liberation Council, made up of four army and four police officers, to run the country.

By 1966, Nkrumah’s government had accumulated years of mounting problems. Ghana, the first sub-Saharan African country to gain independence in 1957, had built impressive infrastructure under his rule, including the Akosombo Dam, but heavy state spending and ambitious industrialization projects had left the country with serious foreign debt. A 1961 nationalization drive tightened state control over the economy, and by the early 1960s shortages, price increases, and public discontent were widespread. Nkrumah had also increasingly concentrated political power in his own hands, declaring Ghana a one-party state under his Convention People’s Party in 1964 and surviving several assassination attempts that pushed him toward greater reliance on internal security services, moves that alienated segments of the military and civil service.

The question of direct American involvement in the coup has been debated for decades and remains genuinely contested among historians rather than settled fact. Declassified CIA cables from the period show that American intelligence was closely tracking coup plotting inside Ghana beforehand and was in some form of contact with plotters, and a 1978 New York Times report cited unnamed intelligence sources describing CIA advice and support to the plotters. Some scholars, drawing on these documents, argue Washington played an active facilitating role, motivated by Cold War concern over Nkrumah’s socialist policies and his close ties to the Eastern bloc and China. Other historians caution that Ghanaian officers had their own well-documented domestic grievances, economic and otherwise, and argue the coup would likely have happened with or without American encouragement. Both strands of evidence appear across the academic literature, and no consensus verdict exists.

Nkrumah never returned to Ghana. He spent his remaining years in exile, first as an honorary co-president of Guinea, and died in Bucharest, Romania, in 1972 while undergoing medical treatment. The National Liberation Council dissolved his party, suspended the constitution, and set the country on a path toward the civilian Second Republic under Kofi Busia a few years later, though Ghana would continue cycling between civilian and military rule for another quarter century.

Nkrumah’s overthrow remains one of the most consequential events in Ghana’s post-independence history and a touchstone in wider African debates over Cold War-era interference in the continent’s politics. Regardless of exactly how much external hands shaped the outcome, the coup abruptly ended the rule of one of Pan-Africanism’s most prominent founding figures and marked Ghana’s first, but far from last, experience of a military takeover.
