The 1812 constitution established the office of governor, to serve for four years starting from the fourth Monday after the election. In 1845, the start date was moved to the fourth Monday of the January after the election; in 1864, it was moved to the second Monday of the January after the election; in 1879 it was moved to the first Monday after the General Assembly announced the election result; the 1921 Constitution fixed the new inauguration date as the second Tuesday in May. The 1974 Constitution changed the date, effective in 1980, to the second Monday of the March following the election; this was amended in 1987, to become effective in 1992, to the second Monday of January. Governors were not allowed to succeed themselves until 1864, when the constitution held no term limits. The restriction on governors succeeding themselves was reintroduced in 1868, removed again in 1879, and again added in 1898. An amendment to the constitution passed in 1966 allowed governors to succeed themselves once before requiring a gap before they can be elected again. Governors of Louisiana can only serve two consecutive terms, but can serve again after being out of office for one term; more than half of one full four year term is considered a term as well. Five governors have served nonconsecutive terms. Andre B. Roman, Francis T. Nicholls, and Jimmie Davis each served two non-consecutive terms, while Earl Long and Edwin Edwards both served in three distinct stints.
