Upon his return to Mississippi, he was elected to the state senate representing his native county, serving from 1839 to 1844. In 1846, he moved to Sunflower County, Mississippi, and founded Itta Bena. He developed a cotton plantation there.
Civil War
During the American Civil War, Humphreys raised a company and was commissioned a captain in the Confederate States Army in 1861. Part of the 21st Mississippi Infantry Regiment, he was elected to the rank of colonel the same year and brigaded with other regiments under the command of Brig. Gen. William Barksdale in the Eastern Theater. At the Battle of Gettysburg in 1863, Humphreys's regiment was part of the force that attacked U.S. Army positions at the Peach Orchard, driving the U.S. soldiers back toward Cemetery Ridge. Humphreys took command of the brigade after the death of Barksdale. He was subsequently promoted to brigadier general,[1] and remained in command until he was wounded in the battle of Berryville, Virginia, on September 3, 1864. Humphreys returned home to Mississippi to heal but could not return to active duty before the war ended.
Political career
Confederate surrender in 1865 was followed by Reconstruction of state governments. Secessionist officials and military officers were forbidden to hold public office in the United States unless pardoned. Benjamin Humphreys was unpardoned when he announced his candidacy for Mississippi governor as a Democrat. PresidentAndrew Johnson did not want him elected and refused to pardon him. Humphreys persisted in his candidacy, won the election on 2 October 1865, and was inaugurated and sworn in as Governor on 16 October. On 26 October, provisional Governor William L. Sharkey received from President Johnson a pardon for Humphreys. Humphreys won re-election to a second term in 1868.
However, Republicans in Congress took control of Reconstruction, and on 15 June, he was physically removed from office by soldiers of the U.S. Army.[2]
As a Democratic Governor of the State of Mississippi, he professed the ideology of White supremacy. In his own words:
The Negro is free, whether we like it or not; we must realize that fact now and forever. To be free, however, does not make him a citizen, or entitle him to political or social equality with the white race.
After he retired from politics, Humphreys entered a career in insurance in Jackson, Mississippi. He continued there until his retirement in 1877, when he moved to his plantation in Leflore County, Mississippi, where he died in 1882. He is buried in Wintergreen Cemetery, Port Gibson, Mississippi.[3]
