 The government forces had superior manpower and weapons but the RPF fought tactically, and were able to exploit the fact that the government forces were concentrating on the genocide rather than the fight for Kigali.The RPF took control of Kigali on 4 July, a date now commemorated as the Liberation Day national holiday.Since the war and genocide the city has experienced rapid population growth as a result of migration from other areas, as well as a high birth rate.
