Flag of Rhodesia
The Flag of Rhodesia (now Zimbabwe) changed many times as a result of political changes in the country.
In 1953, Southern Rhodesia federated with Northern Rhodesia and Nyasaland as the Federation of Rhodesia and Nyasaland. The flag of that federation was used until 31 December 1963 when the federation was dissolved. Less than a year after the break-up of the Federation of Rhodesia and Nyasaland, Northern Rhodesia and Nyasaland became independent as Zambia and Malawi. Southern Rhodesia became known simply as Rhodesia. In April 1964 Rhodesia adopted a light air force ensign with the shield from the coat of arms of Rhodesia in the fly. This was the first time the lighter shade of blue ensign was used by a British colony, although Fiji and Tuvalu both adopted the colour after independence.
Following the Unilateral Declaration of Independence (UDI) on 11 November 1965, the flag was retained, but three years later on the anniversary of UDI it was replaced by a green and white flag (similar to that of Nigeria) with the full coat of arms in the centre. On 2 March 1970, the country was declared a republic. Throughout this time, Britain refused to recognise Rhodesia's independence and maintained that the light-blue ensign was the official flag of the country.
In 1979, the country became known as Zimbabwe-Rhodesia and a new flag was adopted on 2 September that year featuring the pan-African colours of red, black, yellow and green, and the Zimbabwe Bird. However, under the terms of the Lancaster House Agreement, the country briefly returned to British rule under the Union Jack from 12 December 1979 although the new flag remained de facto in use. Thus it was the British Union Flag that was lowered during the ceremony on 18 April 1980 marking the country's attainment of independence as the Republic of Zimbabwe.

Flag of the Governor of Southern Rhodesia 
The flag used by the Governor of Southern Rhodesia followed the usual pattern for representatives of the British Crown. It consisted of a defaced Union Flag (Union Jack) with a white disc in the center of the flag. Within the center of the disc was the shield from the Southern Rhodesian Coat of Arms. This flag was not used during the Unilateral Declaration of Independence (UDI) years and became obsolete when the post of Governor disappeared after the independent Republic of Zimbabwe came into being in 1980.
In most of the British colonies the flags used by the Sovereign's representative usually followed the same general design. In Southern Rhodesia, the Governor was appointed by the Crown and acted as the local head of state, receiving instructions from the British Government. The Governor was also Commander-in-Chief of the armed forces and as such, in theory at least, exercised considerable influence over the running of the colony and its government. In practice, however, the Governor's main function was to maintain a satisfactory relationship between the British and Southern Rhodesian Governments and acted in an advisory capacity most of the time.
In Southern Rhodesia, the Governor initially flew a Union Flag with a white roundel in the centre charged with the shield from the colony's arms granted on 11 August 1924. Unique among the flags of the Governors of British Colonies, this shield of Arms was not surrounded by the customary wreath. Southern Rhodesia became a British Colony on 12 September 1923. This flag was put into use on 1 October 1924 and was flown until 30 July 1951.
On 31 July 1951, a new flag was put into use for the Governor of Southern Rhodesia. This was dark blue and charged in the centre with a Royal Crown, its height being four-sevenths of the hoist. Initially the Tudor Crown would have been used, but after her accession to the throne in 1952, Queen Elizabeth II indicated her preference for St Edward's Crown and this version would have been used thereafter. Like its predecessor, this flag did not conform to the usual pattern of the flags used by British Colonial Governors which was to have dark blue flag charged in the centre with the Royal Crest above a Crown, with the name of the Colony or Dominion written in a yellow scroll below. The reason for Southern Rhodesia not conforming to this pattern is probably explained by the unique Constitutional Status of the colony, having attained 'Responsible Government' in 1923, but not being a fully fledged Dominion.
