Encouraged by the Pan-Africanists, Hutu advocates in the Catholic Church, and by Christian Belgians (who were increasingly influential in the Congo), Hutu resentment of the Tutsi increased. The United Nations mandates, the Tutsi elite class, and the Belgian colonialists added to the growing unrest. Grégoire Kayibanda, founder of PARMEHUTU, led the Hutu "emancipation" movement. In 1957, he wrote the "Hutu Manifesto". His party quickly became militarized. In reaction, in 1959 the Tutsi formed the UNAR party, lobbying for immediate independence for Ruanda-Urundi, to be based on the existing Tutsi monarchy. This group also became militarized. Skirmishes began between UNAR and PARMEHUTU groups. In July 1959, when the Tutsi Mwami (King) Mutara III Charles died following a routine vaccination, some Tutsi thought he had been assassinated. His younger half-brother became the next Tutsi monarch, Mwami (King) Kigeli V.
