↑The government recognised Queen Elizabeth II as the official Head of State from 1965 to 1970. The highest official of Rhodesia held the title "Officer Administering the Government" (OAtG) as he acted in lieu of the official Governor, who remained at his post but was ignored. After Rhodesia became a republic in March 1970, the President replaced the OAtG as the highest official and the Governor returned to London.
The official name of the country under British law was "Southern Rhodesia", but the government in Salisbury used the name "Rhodesia" instead. This situation dated back to October 1964, when the colony of Northern Rhodesia changed its name to Zambia following independence, so the colonial government felt that "Southern" Rhodesia should no longer be used because there was no "Northern" Rhodesia. However, Britain believed that only their government could change the colony's name and not the colony itself.
History
Unilateral Declaration of Independence (UDI)
The British government adopted a policy called no independence before majority rule, which dictated that colonies with a certain amount of white settlers would not become independent until they adopted a policy of majority rule. This had conflicted with the beliefs of the white minority Rhodesian Front, lead by Ian Smith, which believed that Rhodesia should become an independent country anyway. This continued until relations between the colony and the British government broke down in 1965.
Rhodesia sought international recognition as a Commonwealth realm, with Queen Elizabeth II as "Queen of Rhodesia", but later severed it links to the British Crown by becoming a republic on 2 March 1970.
The Bush War
As early as 1960, many African nationalists began to challenge Rhodesia's minority rule policies. In 1964, tensions boiled over and the Rhodesian Bush War began. On one side, the minority rule government, led by Ian Smith, hoped to keep the whites in power. On the other side, the ZANU-PF, led by Robert Mugabe, fought for majority rule. After about 15 years of fighting, the Lancaster House Agreement was signed which allowed majority rule. This led to Zimbabwe's independence.
