In 1994, the Uganda government and rebels increasingly involved themselves in conflicts in Zaire, Sudan, and Rwanda. As warfare spread across borders in central Africa, rebel groups exploited the chaos to gain international supporters and spread their influence. The western Ugandan rebels grew dramatically in strength from 1994, as Sudan began to support them. Most importantly, the LRA's rebellion intensified and expanded in scope once again. With Sudanese support, the LRA grew to over two thousand well-armed fighters by March 1994, allowing it to raid all of northern Uganda, displacing hundreds of thousands. The Sudanese government also set up new rebel groups and organized the merger of insurgent factions; most notably, remnants of NALU, UMFF, UMLA, and others formed the Allied Democratic Forces (ADF) that consequently waged a decades-long insurgency. With Sudanese aid, new rebellions broke out in the West Nile region which persisted until the early 2000s. In turn, Uganda invaded Zaire and Sudan as part of the First Congo War and the Second Sudanese Civil War, partially in an attempt to destroy the rear bases of Ugandan rebels.
