Who Killed Patrice Lumumba? The CIA Plot and the Katangan Execution

Patrice Lumumba’s death on January 17, 1961, resulted from two distinct chains of events that are often collapsed into one: a CIA plot that never reached its target, and a killing carried out on the ground by Congolese and Belgian actors who were not, on the available record, executing that specific plot.

By August 1960, senior US officials viewed Lumumba, Congo’s first prime minister, as a dangerous Cold War liability after he sought Soviet military assistance amid the chaos following independence. The 1975 US Senate Church Committee, formed to investigate American intelligence abuses, later documented that the CIA developed a plan to assassinate Lumumba by poison: station chief Larry Devlin received a vial of poison and instructions from CIA headquarters, reportedly delivered by scientist Sidney Gottlieb, intended to be introduced into Lumumba’s food or toothpaste. The committee found evidence, including a recollection by a National Security Council staffer that President Eisenhower, in an August 1960 meeting, said something to the effect that Lumumba should be “eliminated,” supporting what it called a “reasonable inference” that the plot was authorized at the highest level. The committee stopped short of a definitive finding, citing gaps and ambiguity in the surviving record, but its account remains the most authoritative acknowledgment of White House-level intent to kill Lumumba.

That plot, however, was never carried out. Devlin ultimately did not use the poison, and historians who have examined the record, including the Church Committee itself, concluded the CIA was not directly responsible for the killing that actually took place.

The killing itself followed a separate track rooted in Congolese and Belgian politics. Colonel Joseph Mobutu, who had seized effective power in a September 1960 coup, had Lumumba arrested in December 1960 after he attempted to flee house arrest in Léopoldville. In mid-January 1961, Mobutu’s government transferred Lumumba, along with allies Joseph Okito and Maurice Mpolo, to Katanga, the mineral-rich province that had seceded under Moïse Tshombe with Belgian backing, where the three men were known to face near-certain death. They were beaten during the flight and, hours after arrival on the evening of January 17, executed by firing squad. Katangan gendarmes shot Okito and Mpolo, while accounts drawing on Belgian parliamentary and judicial investigations describe a Belgian officer directing or personally carrying out Lumumba’s execution, with Tshombe and other Katangan leaders present. Mobutu himself was not at the scene.

Belgium’s own 2001 parliamentary inquiry concluded that Belgian officials bore a share of “moral responsibility” for creating the conditions that led to Lumumba’s death, without alleging that Brussels had ordered the specific act carried out in Katanga that night. The result is a killing with genuinely dual authorship in the historical record: a US-authorized plot against Lumumba’s life that stalled before execution, and a Belgian-facilitated, Katangan-carried-out killing that succeeded: two threads of the same Cold War intervention in Congo’s sovereignty, but not, as far as declassified evidence shows, a single unbroken chain of command from Washington to the execution site.

What happened to Lumumba’s body deepened the sense of desecration. Belgian police commissioner Gerard Soete, brought in to dispose of the remains, later admitted he and his brother dismembered the body and dissolved it in sulphuric acid so no grave could ever become a shrine, keeping a gold-capped tooth as a personal memento. Belgian authorities seized that tooth from Soete’s daughter in 2016 after a complaint from Lumumba’s family, and in June 2022, sixty-one years after the killing, Belgian prime minister Alexander De Croo formally returned it to Lumumba’s relatives in a Brussels ceremony, the only physical remains of Congo’s first prime minister ever recovered. Former CIA officer John Stockwell, who served in the Congo station and later became a prominent agency whistleblower, added his own account in a 1978 memoir, writing that the CIA’s base chief in Elizabethville was in direct contact with the men holding Lumumba on the night he was killed, an on-the-ground detail that, while not proof of a CIA trigger, reinforced how closely US intelligence tracked, and how little it did to stop, the killing it had itself once plotted.
