Zimbabwe Rhodesia was the final, greatest attempt at a true compromise between the white minority government of Rhodesia and blacks in the country who wanted majority rule.
In 1979, a new constitution created the nation's first black majority electorate, while still giving certain political protections to the new nation's white minority. A black majority parliament and a black president, Abel Muzorewa, were elected. Muzorewa wanted to lead a true multi-racial, tolerant nation that could avoid the fall to violence, dictatorship, and economic turmoil that so many African nations suffered at the time.
Unfortunately the international community refused to give Zimbabwe Rhodesia any more recognition than they had given the much more racially stratified Rhodesia. The biggest blow came when the USA and Britain didn't support the new country for fear of alienating international allies.
Zimbabwe Rhodesia lasted just six months before the country was reorganized again and the British oversaw an election that saw Robert Mugabe come to power. Voter intimidation was ignored because the British believed Mugabe would have won anyway.
Many western pundits believed this would bring an end to the nation's racial strife. In reality, it destroyed the last chance for true peaceful racial coexistence in Zimbabwe. Mugabe's government oversaw ethnic cleansing of not just whites, but minority black Ndebele civilians, political oppression, and the ruin of Zimbabwe's once thriving economy.
