Patrice Lumumba is arrested by Mobutu Sese Seko's men on the banks of the Sankuru River, for inciting the army to rebellion.

Patrice Émery Lumumba was a Congolese politician and independence leader who served as the first prime minister of the Democratic Republic of the Congo from June until September 1960, following the May 1960 election. He was the leader of the Congolese National Movement (MNC) from 1958 until his assassination in 1961. Ideologically an African nationalist and pan-Africanist, he played a significant role in the transformation of the Congo from a colony of Belgium into an independent republic.

Mobutu Sese Seko Kuku Ngbendu wa za Banga, often shortened to Mobutu Sese Seko or Mobutu and also known by his initials MSS, was a Congolese politician and military officer who was the first and only president of Zaire from 1971 to 1997. Previously, Mobutu served as the second president of the Democratic Republic of the Congo, from 1965 to 1971. He also served as the fifth chairperson of the Organisation of African Unity from 1967 to 1968. During the Congo Crisis in 1960, Mobutu, then serving as Chief of Staff of the Congolese Army, deposed the nation's democratically elected government of Patrice Lumumba with the support of the U.S. and Belgium. Mobutu installed a government that arranged for Lumumba's execution in 1961, and continued to lead the country's armed forces until he took power directly in a second coup in 1965.
