Helfen Sie mir, das Jahr dieser Karte zu bestimmen

Yugoslavia 1918 to 1992,

Transkei 1976 to 1994

Namibia 1915 to 1990

Zimbabwe renamed from Rhodesia in 1980

Best I can draw is 1976-1980

Edit: u/Src267 has noted that the Central African empire was abolished in 1979

u/Francois_TruCoat has noted that Djibouti was a republic post 1977

Were down to 1977-1979

Specifically June 1977 – September 1979

Has Djibouti as a republic so post 27 June 1977: Burkina Faso is still Upper Volta so before 4 August 1984.

Transkei, so after 1976
Central African Empire so before 1979

So, 1976-1979

Between 1976 (when Transkei was established) but before the Camp David Accords in 1978 (returning the Sinai to Egypt, in phases).
