Twenty-eight individuals have held the office of governor of New Mexico since the state's admission to the Union in 1912, two of whom—Edwin L. Mechem and Bruce King—served three non-consecutive terms. King holds the record as New Mexico's longest-serving governor, with 12 years of service. William C. McDonald, the first governor, took office on January 15, 1912. The first woman to serve as Governor was RepublicanSusana Martinez, who served from 2011-2019. The current officeholder is Michelle Lujan Grisham, who took office on January 1, 2019, as the first elected female Democratic governor of the state.
On August 18, 1846, American forces led by Stephen W. KearnycapturedSanta Fe, capital of the Mexican territory of Santa Fe de Nuevo México.[1] A code of laws known as the Kearny Code was established on September 22, 1846.[2] The region remained under military control until formally annexed by the United States on July 4, 1848. Following Kearny's departure for California on September 26, the chief military officer in the territory was Col. Sterling Price until October 11, 1848; Lt. Col. John M. Washington until October 23, 1849; and Col. John Munroe until the territory was organized.
Kearny appointed Charles Bent as governor before he left for California; Bent would be assassinated during the Taos Revolt on January 19, 1847. Col. Price appointed Donaciano Vigil as acting governor. A statehood convention chose Henry Connelly as governor on June 20, 1850, but this was never recognized by the federal government.
Territory of New Mexico
New Mexico Territory was organized on December 13, 1850.[3] It would remain a territory for 62 years.
The state constitution of 1912 called for the election of a governor and lieutenant governor every four years. The term was changed to two years by a 1914 amendment, and lengthened back to four years in 1970. Governors originally could not succeed themselves; this was changed in 1914 to allow governors to succeed themselves once before having to take a term off. With the lengthening of the term to four years in 1970, this was changed back to prohibiting them from succeeding themselves, but in 1986 it was lengthened back to two terms. A 1962 amendment made it so that the governor and lieutenant governor are elected on a ticket (election).[68] In the event of a vacancy in the office of governor, the lieutenant governor becomes governor.[69]
