Georgia lawyer and politician In 1845, a few months before his twentieth birthday, Lamar moved to
Macon, Georgia, where he studied law in his uncle's office for two years. He was admitted to the Georgia bar in 1847 in
Vienna. Afterwards, Lamar moved back to
Covington, where he set up his own legal practice. Using family connections associated with the Longstreet name, Lamar took his first steps into politics when
Newton County sent him as a delegate to the state
Democratic convention in
Milledgeville in 1847 and 1849. When that convention discussed the
Wilmot Proviso, Lamar embraced a staunch
proslavery position that he never changed throughout the
antebellum period.
Mississippi lawyer, slaveowner and politician Lamar moved to
Oxford,
Mississippi, in 1849 after A.B. Longstreet became president of the
University of Mississippi. In June 1850, Lamar received a license to practice law in Mississippi, and in July, he became the university's assistant professor of mathematics. In the November, 1850 federal census, Lamar owned 14 slaves near Oxford (almost all women and girls) compared to Longstreet's 10 slaves (almost all adults). A decade later, after his brief return to Georgia described below, Lamar owned 31 slaves in Lafayette County, Mississippi, of whom 14 were female and 17 male, including 9 boys and 4 girls under 10. Lamar's political career in Mississippi began in May 1850, when he addressed a
Lafayette County convention on the topic of slavery. In March 1851, he helped organize a local branch of the
Southern Rights Party in Oxford and soon became its delegate to the statewide party convention in Jackson. Lamar campaigned on behalf of party candidate
Jefferson Davis for governor and was the party's spokesman in a debate in Oxford with
Unionist opponent
Henry Foote. Despite Lamar's efforts, Foote defeated Davis by 999 votes.
Return to Georgia as lawyer and legislator Homesick and dissatisfied as a politician, in the summer of 1852, Lamar returned to Covington and entered into a legal partnership with a friend. Lamar reentered politics in Georgia by winning a seat in the
Georgia House of Representatives as a member of the
Democratic Party in Newton County, which had typically favored
Whig candidates. Lamar became chairman of the Committee on the State of the Republic and also served on the Agriculture and Internal Improvements, Judiciary, and Public Printing committees, as well as on two special committees. Throughout the 1853–1854 term, he focused on issues dealing with the
Western and Atlantic Railroad, party politics and slavery. In February 1854, after the legislative term ended, Lamar moved to Macon to open a law office. With support from former congressman
A. H. Chappell, Lamar sought the Democratic nomination in 1855 for
Georgia's 3rd congressional district but failed to gather enough votes at the convention to become his party's candidate.
Return to Mississippi and Congressman (1857–1860) After losing that Georgia congressional campaign, and facing financial troubles as well as family responsibilities, Lamar left Georgia for the final time and returned to Lafayette County, Mississippi. Along the
Tallahatchie River north of
Abbeville, Lamar established his "Solitude" cotton plantation that by 1857 had 26 slaves, though the plantation was never fully developed. Lamar also practiced law in nearby
Holly Springs with two local prominent lawyers, C. M. Mott and James L. Autrey. In 1857, Democratic Congressman
Daniel Wright decided not to seek reelection in
Mississippi's 1st congressional district.
The Memphis Daily Appeal suggested Lamar as a possible candidate under the Democratic ticket, though he faced difficulties due to his prior support of
Howell Cobb, a leader of the Union movement. Nevertheless, at this convention, after numerous indecisive ballots, Mississippi Democrats made Lamar their candidate, and Lamar credited his old friend
Jacob Thompson for the win. Lamar campaigned against Whig opponent,
James Lusk Alcorn by stressing his strong support of the
Kansas-Nebraska bill, and won by a comfortable margin, then two years later faced no opponent and thus easily won reelection. Lamar's antebellum congressional career primarily focused on
sectionalist issues, especially protecting Southern interests in slavery. Lamar supported the proslavery
Lecompton Constitution in Kansas without
popular ratification, which was the subject of a debate on the House floor on the morning of February 6, 1858. When a South Carolina congressman attacked a Pennsylvania Republican congressman, a brawl ensued, with Lamar attacking Illinois congressman (and Congregational minister)
Owen Lovejoy, who had become a prominent abolitionist after a pro-slavery mob killed his brother. Lamar supported the compromise
English Bill created by southerners and President
Buchanan. Lamar again defended slavery as an institution verbally in an 1860 speech, during which he argued that not everyone is equal. While Lamar never directly advocated for
secession, he mentioned it as possible if the South lost the ability to check the majority
abolitionist opinion in the government. After the victory of Republican candidate Abraham Lincoln in the November 1860 presidential election was clear, Lamar left Washington on December 12, 1860, to canvass for a seat in the upcoming Mississippi secession convention. On January 12, 1861, Lamar resigned from Congress, as did all other members of the Mississippi delegation. == Secession ==
