The British influenced and affiliated federation and its institutions and racial relations differed from the only other regional power, the Union of South Africa. The dissolution of the CAF highlighted the discrepancy between the independent African-led nations of Zambia and Malawi, and Southern Rhodesia (which remained ruled by a White minority government until the Internal Settlement in 1978). Southern Rhodesia soon found itself embroiled in a civil war between the Government and African nationalist and Marxist guerrillas, whereas both Malawi and Zambia developed into authoritarian one-party states and remained so up until the post-Cold War era.
