Wilson became active politically as a
Whig, and campaigned for
William Henry Harrison in 1840. He had joined the Whigs out of disappointment with the fiscal policies of Democrats
Andrew Jackson and
Martin Van Buren, and like most Whigs blamed them for the
Panic of 1837. In 1840 he was also elected to the
Massachusetts House of Representatives, and served from 1841 to 1843. Wilson was a member of the
Massachusetts State Senate from 1844 to 1846 and 1850 to 1852. From 1851 to 1852 he was the Senate's
President. As early as 1845, Wilson had started to become disenchanted with the Whigs as the party attempted to compromise on the slavery issue, and as a
Conscience Whig he took steps including the organization of a convention in
Concord opposed to the annexation of
Texas because it would expand slavery. As a result of this effort, in late 1845 Wilson and abolitionist
John Greenleaf Whittier were chosen to submit in person a petition to Congress containing the signatures of 65,000 Massachusetts residents opposed to Texas annexation. Wilson was a delegate to the
1848 Whig National Convention, but left the party after it nominated slave owner
Zachary Taylor for president and took no position on the
Wilmot Proviso, which would have prohibited slavery in territory acquired from Mexico in the
Mexican–American War. Wilson and
Charles Allen, another Massachusetts delegate, withdrew from the convention, and called for a new meeting of anti-slavery advocates in
Buffalo, which launched the
Free Soil Party. Having left the Whig Party, Wilson worked to build coalitions with others opposed to slavery, including Free Soilers, anti-slavery Democrats,
Barnburners from New York's Democratic Party, the
Liberty Party, the anti-slavery elements of the Whig Party, and anti-slavery members of the
Know Nothing or Native American Party. Although Wilson's new political coalition was initially castigated by "straight party" adherents of the mainstream Democratic and Whig parties, Wilson was successful in an effort to broker an alliance between the minority Free Soil and Democratic parties in the state elections of 1850, notably resulting in the election of
Charles Sumner to the Senate. ,
Henry Ward Beecher,
Wendell Phillips,
William Lloyd Garrison,
Gerrit Smith,
Horace Greeley, and Henry Wilson. From 1848 to 1851 Wilson was the owner and editor of the
Boston Republican, which from 1841 to 1848 was a Whig outlet, and from 1848 to 1851 was the main Free Soil Party newspaper. During his service in the Massachusetts legislature, Wilson took note that participation in the state militia had declined, and that it was not in a state of readiness. In addition to undertaking legislative efforts to provide uniforms and other equipment, in 1843 Wilson joined the militia himself, becoming a major in the 1st Artillery Regiment, which he later commanded with the rank of
colonel. In 1846 Wilson was promoted to
brigadier general as commander of the Massachusetts Militia's 3rd Brigade, a position he held until 1852.
Free Soil Party organizer In 1852, Wilson was chairman of the Free Soil Party's national convention in
Pittsburgh, which nominated
John P. Hale for president and
George Washington Julian for vice president. Later that year he was a Free Soil candidate for
U.S. Representative, and lost to Whig
Tappan Wentworth. He was a delegate to the
state constitutional convention in 1853, which proposed a series of political and governmental reforms that were defeated by voters in a post-convention popular referendum. He ran unsuccessfully for
Governor of Massachusetts as a Free Soil candidate in 1853 and 1854, but declined to be a candidate again in 1855 because he had his sights set on the U.S. Senate.
U.S. Senator (1855–1873) In 1855 Wilson was elected to the
United States Senate by a coalition of
Free-Soilers,
Know Nothings, and anti-slavery
Democrats, filling the vacancy caused by the resignation of
Edward Everett. He had briefly joined the Know-Nothings in an attempt to strengthen their anti-slavery efforts, but aligned himself with the Republican Party at its creation, formed largely along the lines of the anti-slavery coalition Wilson had helped develop and nurture. Wilson was reelected as a Republican in 1859, 1865 and 1871, and served from January 31, 1855, to March 3, 1873, when he resigned in order to begin his vice presidential term on March 4. In his first Senate speech in 1855, Wilson continued to align himself with the abolitionists, who wanted to immediately end slavery in the United States and its territories. In his speech, Wilson said he wanted to abolish slavery "wherever we are morally and legally responsible for its existence", including Washington, D.C., Wilson also demanded repeal of the
Fugitive Slave Act of 1850, believing the federal government should have no responsibility for enforcing slavery, and that once the act was repealed tensions between slavery proponents and opponents would abate, enabling those Southerners who opposed slavery to help end it in their own time. On May 22, 1856,
Preston Brooks brutally assaulted Senator
Charles Sumner on the Senate floor, leaving Sumner bloody and unconscious. Brooks had been upset over Sumner's
Crimes Against Kansas speech that denounced the
Kansas–Nebraska Act. After the beating, Sumner received medical treatment at the Capitol, following which Wilson and
Nathaniel P. Banks, the
Speaker of the House, aided Sumner to travel by carriage to his lodgings, where he received further medical attention. Wilson called
the beating by Brooks "brutal, murderous, and cowardly". Brooks immediately challenged Wilson to a duel. Wilson declined, saying that he could not legally or by personal conviction participate. In reference to a rumor that Brooks might attack Wilson in the Senate as he had attacked Sumner, Wilson told the press "I have sought no controversy, and I seek none, but I shall go where duty requires, uninfluenced by threats of any kind." The rumors proved unfounded, and Wilson continued his Senate duties without incident. The attack on Sumner took place just one day after pro-slavery Missourians killed one person in the burning and sacking of
Lawrence, Kansas. The attack on Sumner and the sacking of Lawrence were later viewed as two of the incidents which symbolized the "breakdown of reasoned discourse." This phrase came to describe the period when activists and politicians moved past the debate of anti-slavery and pro-slavery speeches and non-violent actions, and into the realm of physical violence, which in part hastened the onset of the
American Civil War. In June 1858 Wilson made a Senate speech in which he suggested corruption in the government of California and implied complicity on the part of Senator
William M. Gwin, a pro-slavery Democrat who had served as a member of Congress from Mississippi before moving to California. Gwin was backed by a powerful Southern coalition of pro-slavery Democrats called the Chivs, who had a monopoly on federal patronage in California. Gwin accused Wilson of demagoguery, and Wilson responded by saying he would rather be thought a
demagogue than a thief. Gwin then challenged Wilson to a duel; Wilson declined in the same terms he used to decline a duel with Preston Brooks. In fact neither Gwin nor Wilson wanted to follow through, and commentary about the dispute broke down along partisan lines. One pro-Gwin editorial called the insinuation that Gwin was corrupt "a most malignant falsehood", while a pro-Wilson editorial called his reluctance to take part in a duel evidence that he was "honest" and "conscientious", and had "more respect for the laws of this country than his adversary". After several attempts to find a face-saving compromise, Gwin and Wilson agreed to refer their dispute to three senators who would serve as mediators.
William H. Seward,
John J. Crittenden and
Jefferson Davis were chosen, and produced an acceptable solution. At their instigation, Wilson stated to the Senate that he had not meant to impugn Gwin's honor, and Gwin replied by saying that he had not meant to question Wilson's motives. In addition, the mediators caused to be removed from the Senate record both Gwin's remarks about demagoguery and Wilson's suggestion that Gwin was a thief. ==Civil War==
