The victorious RPF assumed control of the country, with Paul Kagame as "de facto" leader. Kagame served as vice president from 1994 and as president from 2000. The RPF began a programme of rebuilding the infrastructure and economy of the country, bringing genocide perpetrators to trial, and promoting reconciliation between Hutu and Tutsi. In 1996 the RPF-led Rwandan Government launched an offensive against refugee camps in Zaire, home to exiled leaders of the former regime and millions of Hutu refugees. This action started the First Congo War, which removed long-time dictator President Mobutu Sese Seko from power. As of 2020, Kagame and the RPF remain the dominant political force in Rwanda.
