Career
In 1840, Minor was admitted to the bar and began the practice of law in Stamford. Minor became a member of the Connecticut House of Representatives in 1841, and served in that position until 1848. He was a judge for the Fairfield County, Connecticut Court. He married Mary Catherine Leeds on April 16, 1849, and they had five children. He became a member of the Connecticut State Senate representing the 12th District in 1854. As candidate of the American Party, Minor was elected Governor of Connecticut in 1855 over Samuel Ingham by the Connecticut General Assembly by a 177 to 70 vote. He was re-elected to a second term in 1856 by the Connecticut General Assembly, again over Ingham, by a vote of 135 to 116. While Governor, Minor was a supporter of lengthening the period of residency before naturalization. He also supported the dismissal of six military companies that consisted mostly of Irishmen. This step further enraged immigrants. Legislation was passed that deprived suffrage to men unable to read the state constitution. He supported better schools in Connecticut and held the belief that the schools should be free for all the children in the state. He also supported the antislavery measures of the Republicans. He was not a candidate for the governorship in the election of April 1857, and left office on May 6, 1857. In 1864, Minor was a delegate from Connecticut to the Republican National Convention, which assembled at Baltimore in June of that year. He voted with his delegation for Abraham Lincoln for President and Andrew Johnson for Vice-President of the United States. In July 1864, Minor was appointed by Lincoln as Consul-General to Havana, Cuba. Three years later he returned to Connecticut and spent one year as a member of the Connecticut House of Representatives. In 1868, he was appointed judge on the Connecticut Superior Court, and served in that position until 1873 when he resigned his judgeship and returned to his private law practice. He also served on the 1879 commission that reconciled an extended boundary argument with New York.
