The United States and later China provided monetary and material support to the FNLA and under the regime of Joseph Mobutu (later Mobutu Sese Seko), Zaire would send its own troops into Angola to bolster the FNLA's ranks. Due to differences in ideology and ethnic composition the MPLA and FNLA were unable to unite against the Portuguese and fought each other nearly as much as their common enemy.  A third group, UNITA, was founded by Jonas Savimbi in 1966.
