Rhodesia once again falls under British rule after the country's government voted itself out of office through the Constitution of Zimbabwe-Rhodesia Bill. Ian Smith's government had announced a Unilateral Declaration of Independence (UDI) in 1965, heralding 14 years of white settler-rule. The end of UDI was the subject of a whites-only referendum held in January 1979, ahead of elections for a transitional government which brought Josiah Zion Gumede of the United African National Congress (UANC) into power.
