List of governors of Missouri

The governor of Missouri is the head of government of the U.S. state of Missouri and the commander-in-chief of the Missouri National Guard. The governor has a duty to enforce state laws and the power to either approve or veto bills passed by the Missouri Legislature, to convene the legislature and grant pardons, except in cases of impeachment.

The current governor is Republican Mike Parson, who took office on June 1, 2018. He is ineligible to run in the 2024 election-or any future election--since he served more than two years of the unexpired term of predecessor Eric Greitens.

List of governors
Louisiana was purchased from France in 1803, with it being proclaimed in St. Louis in Upper Louisiana on March 10, 1804, by Amos Stoddard, who remained as military commander of the region until October 1, 1804, when Orleans Territory was split from it. The remainder was designated the District of Louisiana and placed under the jurisdiction of Indiana Territory and its governor, William Henry Harrison.

Louisiana Territory and Missouri Territory
The District of Louisiana was organized as Louisiana Territory on July 4, 1805; it was renamed Missouri Territory on June 4, 1812, after the admission of the state of Louisiana. It had four governors appointed by the president of the United States, including both Meriwether Lewis and William Clark of the Lewis and Clark Expedition.

State of Missouri
Missouri was admitted to the union on August 10, 1821.

The original constitution of 1820 created the offices of governor and lieutenant governor, to serve terms of four years without being able to succeed themselves. Terms were shortened to 2 years in 1865, with a limit of serving no more than four out of every six years. They were returned in 1875 to the four-year term and limit on succession of the 1820 constitution, and the term limit changed to two terms in 1965. Originally, the lieutenant governor would act as governor in the event of a vacancy; a 1968 amendment made it so that the lieutenant governor becomes governor in that situation.

A group including the governor, lieutenant governor, and members of the Missouri General Assembly, proclaimed Missouri's secession from the Union on October 31, 1861, and it was admitted to the Confederate States of America on November 28, 1861. The Confederate government elected two governors, but only had any control in the south of the state, and was forced into exile in Marshall, Texas, after the Battle of Pea Ridge in March 1862.

Confederate governors
During the Civil War, after the capture of Jefferson City by the Union, a constitutional convention declared the office then held by Governor Claiborne Fox Jackson to be vacant. In October, Jackson, Lieutenant Governor Thomas Caute Reynolds, and some members of the General Assembly, organized at Neosho and passed an Ordinance of Secession. This Confederate government never displaced the government in Jefferson City, and Missouri remained in the Union through the entire war. Jackson continued on as governor until his death on December 6, 1862, at which time Reynolds took over, serving until he fled to Mexico in June 1865 after the end of the war.
