Governor-general

Vice-regal representative of the head of state in an independent realm or a major colonial state

Governor-general, or governor general, is the title of an official, most prominently associated with the British Empire and the Commonwealth. In the context of the governors-general and former British colonies, governors-general continue to be appointed as viceroy to represent the monarch of a personal union in any sovereign state over which the monarch does not normally reign in person. In the British Empire, governors-general were appointed on the advice of the government of the United Kingdom and were often British aristocracy, but in the mid-twentieth century they began to be appointed on the advice of the independent government of each realm and were citizens of each independent state.
