Katanga. These were joined by a number of smaller parties which emerged as the nationalist movement developed, including the radical ''
Parti Solidaire Africain'' (PSA), and factions representing the interests of minor ethnic groups like the ''
Alliance des Bayanzi'' (ABAZI).
Although it was the largest of the African nationalist parties, the MNC had many different factions within it that took differing stances on a number of issues. It was increasingly polarised between moderate ''évolués'' and the more radical mass membership. A radical faction headed by Iléo and
Albert Kalonji split away in July 1959, but failed to induce mass defections by other MNC members. The dissident faction became known as the MNC-Kalonji (MNC-K), while the majority group became the MNC-Lumumba (MNC-L). The split divided the party's support base into those who remained with Lumumba, chiefly in the
Stanleyville region in the north-east, and those who backed the MNC-K, which became most popular around the southern city of
Élisabethville and among the
Luba ethnic group.

, used force against the rioters—at least 49 people were killed, and total casualties may have been as high as 500. The nationalist parties' influence expanded outside the major cities for the first time, and nationalist demonstrations and riots became a regular occurrence over the next year, bringing large numbers of black people from outside the ''évolué'' class into the independence movement. Many blacks began to test the boundaries of the colonial system by refusing to pay taxes or abide by minor colonial regulations. The bulk of the ABAKO leadership was arrested, leaving the MNC in an advantageous position.

with Belgium; even some Congolese politicians perceived it as unnecessarily provocative. Nevertheless, independence was celebrated across the Congo.
Politically, the new state had a
semi-presidential constitution, known as the ''Loi Fondamentale'', in which executive power was shared between President and Prime Minister in a system known as ''bicephalisme''. Kasa-Vubu was proclaimed President, and Lumumba Prime Minister, of the Republic of the Congo. Despite the objections of CONAKAT and others, the constitution was largely centralist, concentrating power in the central government in Léopoldville, and did not devolve significant powers to provincial level.
Beginning of the crisis
''Force Publique'' mutiny, racial violence and Belgian intervention
Despite the proclamation of independence, neither the Belgian nor the Congolese government intended the colonial social order to end immediately. The Belgian government hoped that whites might keep their position indefinitely. The Republic of the Congo was still reliant on colonial institutions like the ''
Force Publique'' to function from day to day, and white technical experts, installed by the Belgians, were retained in the broad absence of suitably qualified black Congolese replacements (partly the result of colonial restrictions regarding higher education). Many Congolese people had assumed that independence would produce tangible and immediate social change, so the retention of whites in positions of importance was widely resented.
Lieutenant-General
Émile Janssens, the Belgian commander of the ''Force Publique'', refused to see Congolese independence as marking a change in the nature of command. The day after the independence festivities, he gathered the black

This message was hugely unpopular among the rank and file—many of the men had expected rapid promotions and increases in pay to accompany independence. On 5 July 1960,
several units mutinied against their white officers at Camp Hardy near
Thysville. The insurrection spread to Léopoldville the next day and later to garrisons across the country.
Rather than deploying Belgian troops against the mutineers as Janssens had wished, Lumumba dismissed him and renamed the ''Force Publique'' the ''
