19th-century mansion into a splendid governor's residence. After Volpe resigned to become United States Secretary of Transportation in the Nixon administration, the plan was aborted by his successor in consideration of budgetary constraints and because the location was considered too far from the seat of power, the State House in Boston. Prior to their respective demolitions in 1922 and 1863, the Province House and the Hancock Manor were also proposed as official residences. Since the governor has no official residence, the expression "corner office," rather than "governor's mansion," is commonly used in the press as a metonym for the office of governor. This refers instead to the governor's office on the third floor of the State House. List of governors Since 1780, 65 people have been elected governor, six to non-consecutive terms (John Hancock, Caleb Strong, Marcus Morton, John Davis, John Volpe, and Michael Dukakis), and seven lieutenant governors have acted as governor without subsequently being elected governor. Thomas Talbot served a stint as acting governor, but later was elected governor several years later. Prior to 1918 constitutional reforms, both the governor's office and that of lieutenant governor were vacant on one occasion, when the state was governed by the Governor's Council. Colonial Massachusetts The colonial history of Massachusetts begins with the founding first of the Plymouth Colony in 1620, and then the Massachusetts Bay Colony in 1628. The Dominion of New England combined these and other New England colonies into a single unit in 1686, but collapsed in 1689. In 1692 the Province of Massachusetts Bay was established, merging Plymouth and Massachusetts Bay, which then included the territory of present-day Maine. Colonial governors of Plymouth and the Massachusetts Bay Colony were elected annually by a limited subset of the male population (known as freemen), while Dominion officials and those of the 1692 province were appointed by the British crown. In 1774 General Thomas Gage became the last royally appointed governor of Massachusetts. He was recalled to England after the Battle of Bunker Hill in June 1775, by which time the Massachusetts Provincial Congress exercised de facto control of Massachusetts territory outside British-occupied Boston. Between 1775 and the establishment of the Massachusetts State Constitution in 1780 the state was governed by the provincial congress and an executive council.
