In the immediate aftermath, Belgian authorities laid blame on unemployed Africans, but claimed the majority of the city's 250,000 African residents were not involved. The Belgian Parliament established a commission of inquiry to investigate the cause of the riots. The commission found the disturbances to be the culmination of discontent with racial discrimination, overcrowding, and unemployment. It also concluded that external political events, such as France's decision to grant self-governance to the neighboring French Congo, to be a contributing factor, and criticized the colonial administration's response to the riot. On 13 January the administration went forward with its scheduled announcement of reforms, including new local elections in December, the institution of a new civil service statue that made no racial distinctions, and the appointment of more Africans to advisory bodies. The Belgian King, Baudouin, also declared for the first time that independence would be granted to the Congo in the future. International media assumed that the reforms were made in response to the riots. There is no evidence to support this, though it is possible that Baudouin's declaration was made to temper Congolese opinion.
