<human>: Patrice Emery Lumumba (alternatively styled Patrice Hemery Lumumba; 2 July 1925 - 17 January 1961) was a Congolese politician and independence leader who served as the first Prime Minister of the independent Democratic Republic of the Congo (then Republic of the Congo) from June until September 1960. He played a significant role in the transformation of the Congo from a colony of Belgium into an independent republic. Ideologically an African nationalist and Pan-Africanist, he led the Mouvement National Congolais (MNC) party from 1958 until his death. Shortly after Congolese independence in 1960, a mutiny broke out in the army, marking the beginning of the Congo Crisis.

President Kasa-Vubu began fearing a Lumumbist coup d'etat would take place. On the evening of 5 September, Kasa-Vubu announced over radio that he had dismissed Lumumba and six of his ministers from the government for the massacres in South Kasai and for involving the Soviets in the Congo. Upon hearing the broadcast, Lumumba made his way to the national radio station, which was under UN guard. Though they had been ordered to bar Lumumba's entry, the UN troops allowed the prime minister in, as they had no specific instructions to use force against him. Lumumba denounced his dismissal over the radio as illegitimate, and in turn labeled Kasa-Vubu a traitor and declared him deposed.  He proceeded to Parliament and launched into a debate in which he, in the words of American Ambassador Clare Timberlake, "devastated the points raised by the opposition" and "made Kasa-Vubu look ridiculous." The newly appointed prime minister, Senate leader Joseph Ileo, failed to secure a vote of confidence, which Lumumba won in the Senate on 8 September, 41 to 2 (with 6 abstentions). Still, Parliament did not back Lumumba's dismissal of Kasa-Vubu, creating a constitutional crisis. Numerous African diplomats and newly appointed ONUC head Rajeshwar Dayal attempted to get the president and prime minister to reconcile their differences, but failed. On 13 September, the Parliament held a joint session between the Senate and the Assembly. Though several members short of a quorum, they voted to grant Lumumba emergency powers.  On 14 September, a coup d'etat organised by Colonel Mobutu politically incapacitated both Lumumba and Kasa-Vubu. Lumumba was placed under house arrest on the next day at the Prime Minister's residence. UN troops were positioned around the house to prevent his arrest at the hands of Mobutu's troops, who formed an outer circle around the residence to prevent his escape. On 24 November, the UN voted to recognize Mobutu's new delegates to the General Assembly, disregarding Lumumba's original appointees. Lumumba resolved to join Deputy Prime Minister Antoine Gizenga in Stanleyville and lead a campaign to regain power. Three days later he fled Leopoldville.  With logistical support from the United States and Belgium, Mobutu's troops managed to capture Lumumba in Lodi on 1 December. He was moved to Port Francqui the next day and flown back to Leopoldville. UN forces did not interfere. Mobutu claimed Lumumba would be tried for inciting the army to rebellion and other crimes.
