The governor of West Virginia is the head of government of West Virginia and the commander-in-chief of the state's military forces. The governor has a duty to enforce state laws, and the power to either approve or veto bills passed by the West Virginia Legislature, to convene the legislature at any time, and, except when prosecution has been carried out by the House of Delegates, to grant pardons and reprieves. Since West Virginia was admitted to the Union on June 20, 1863, during the American Civil War, 34 men have served as governor. Two, Arch A. Moore Jr. (West Virginia's 28th and 30th governors) and Cecil H. Underwood (West Virginia's 25th and 32nd governors), served two nonconsecutive terms in office. The longest-serving governor was Moore, who served for three terms over twelve years. The state's first governor after admission into the Union, Arthur I. Boreman, served the most consecutive terms, resigning a week before the end of his third term. Before the state's admission, Francis H. Pierpont, the, "Father of West Virginia," was elected governor during the Wheeling Convention of 1861. Daniel D.T. Farnsworth was senate president at the time; he filled the last seven days of Boreman's term and remains the shortest-serving governor. Underwood has the unusual distinction of being both the youngest person to be elected as governor (age 34 upon his first term in 1957) and the oldest to both be elected and serve (age 74 upon his second term in 1997; age 78 at the end of his second term in 2001). The current governor is Republican Jim Justice, who assumed office on January 16, 2017. West Virginia's 36th governor, Justice was elected as a Democrat, but switched to the Republican Party on August 4 of that year. To serve as governor, a person must be at least 30 years old, and must have been a citizen of West Virginia for at least five years at the time of inauguration. Under the current Constitution of West Virginia, ratified in 1872, the governor serves a four-year term commencing on the Monday after the second Wednesday in the January following an election. The original constitution of 1863 only called for a two-year term. He may be reelected any number of times, but not more than twice in a row. Any partial term served counts toward the limit of two consecutive terms. The constitution makes no mention of a
