Colonial governor
When Newfoundland became an official Crown colony in 1825, Cochrane was appointed as its first governor.[3] At the time, military officers were appointed to direct colonies that did not yet have representative government.[4] He directed the construction of Government House, located between Fort William and Fort Townshend, which has since been designated as a National Historic Site of Canada.[5] He split the colony into three judicial districts over each of which he placed a chief justice and two puisne judges and reinvigorated the poor relief system by building roads.[6]
Although Cochrane had opposed the introduction of representative government to the colony, a new constitution was granted in 1832 and he was appointed as the first civil governor.[4] He became involved in various conflicts while governor, especially with reformers in the new legislature and with the Roman Catholic bishop, Michael Fleming. In 1834, the colonial office recalled Cochrane, who had become unpopular. When he left, he and his daughter were pelted with filth on their way down to the wharf.[4]
