Sovereign countries (2)
Two sovereign UN member states have English names beginning with Z: the Republic of Zambia and the Republic of Zimbabwe. Both sit in southern Africa, share a long border, and draw their names from the same source — the Zambezi, the fourth-longest river on the continent and one of the great defining waterways of the region.
Territories and other entities
No current territories or dependencies have English names beginning with Z. One historical entity is worth noting for completeness: Zaire was the official name (1971–1997) of the country now known as the Democratic Republic of the Congo, listed under C. The renaming followed the fall of Mobutu Sese Seko and the 1997 transition that ended the Zairian state.
