Rhodesia's case is worth commenting on in this context. Independence breached the principle of "no independence before there's majority rule in place" that was being applied to all territories moving toward independence in that period, to ensure a minority of former colonialist descendants didn't continue ruling in London's absence. That's why Rhodesia made their unilateral (white) declaration of independence. As Rhodesia's UDI was under white minority rule, close to apartheid South Africa's, neither the UK nor UN recognised them. From what little I remember, which is mainly the 70s aftermath and rise of China backed Mugabe, just about only South Africa had supported them afterwards.
