 Following the end of British colonial rule in 1961, Julius Nyerere preached the value of Ujamaa, or familyhood, as a basic constituent of Tanzanian nationalism, placing an emphasis on equality and justice.This became a recurring theme in many Tanzanian artists' music, including Remmy Ongala's.His song "Kipenda Roho" was used in Oliver Stone's film "Natural Born Killers".
