Working Men's Party leader During 1829–30, Owen became an active leader in the
Working Men's Party in
New York City. In contrast to
Democratic Presidents Andrew Jackson and
James K. Polk, Owen was opposed to
slavery, although his partisanship distanced him from other leading
abolitionists of the era.
Indiana legislator After Owen's return to New Harmony, Indiana in 1833, he became active in state politics. At the convention, Owen initiated a proposal to include provisions for women's property rights in the state constitution. Although it was not approved, this early effort to protect women's rights led to later laws that were passed to secure women's property, divorce, and voting rights. One of Owen's lasting legacies was his authorship and efforts to secure the inclusion of an article in the
Indiana Constitution of 1851 that provided state funding for a uniform system of common schools that are free and open to all and established the office of the state's superintendent of public instruction.
U.S. Congressman After his first term in the Indiana legislature and two unsuccessful campaigns for election to the
U.S. Congress in 1838 and in 1840, Owen was elected as a Democrat to the
U.S. House of Representatives in 1842. He served from 1843 to 1847 in the Twenty-eighth and Twenty-ninth Congresses. Owen was chairman of the Committee on Roads and Canals during the Twenty-eighth Congress. He was also involved in the debates about the
annexation of Texas and an
Oregon boundary dispute in 1844 that led to the establishment of the U.S-British boundary at the
49th parallel north, the result of the
Oregon Treaty (1846). While serving as a member of Congress, Owen introduced and helped to secure passage of the
bill that founded the
Smithsonian Institution in 1846. Owen was appointed to the Smithsonian Institution's first Board of Regents and chaired its Building Committee, which oversaw the construction of the
Smithsonian Institution Building in
Washington, D.C., and recommended
James Renwick Jr. as architect, James Dixson and Gilbert Cameron as the contractors, and the
Seneca Quarry for its distinct, dark-red sandstone. Owen, his brother
David Dale Owen, and architect
Robert Mills, were involved in developing preliminary plans for the Smithsonian Building. These early plans influenced Renwick's choice of the
Romanesque Revival architectural style (sometimes referred to as
Norman-style architecture) and his three-story design for the building, which was finally selected, although not without controversy. Owen's book
Hints on Public Architecture (1849) argued the case for the suitability of Renwick's Romanesque Revival (Norman) architectural style for public buildings such as the Smithsonian "Castle," which he discussed in detail. Seven full-page illustrations and details of the building's architectural elements were prominently featured in the book, leading some to criticize Owen for his bias toward Renwick and his preference for Norman-style architecture over other popular styles.
U.S. diplomat Owen was defeated in his bid for re-election to Congress in 1846; however, he remained active in public service and was once again elected to serve in the Indiana General Assembly. Owen served in the diplomatic post until 20 September 1858, and then retired from political life, although he remained actively interested in public affairs and social reform issues. In 1862 Owen wrote a series of open letters to U.S. government officials, including President
Abraham Lincoln and
U.S. Secretary of the Treasury Salmon P. Chase, to encourage them to support general emancipation. Owen's letter of 23 July 1862, was published in the
New York Evening Post on 8 August 1862, and his letter of 12 September 1862, was published in the same newspaper on 22 September 1862. In another open letter that Owen wrote to President
Lincoln on 17 September 1862, he urged the president to abolish
slavery on moral grounds. Owen also believed that emancipation would weaken the
Confederate forces and help the Union army win the war. (as he had first resolved to do in mid-July). In
Emancipation is Peace, a pamphlet that Owen wrote in 1863, he confirmed his view that general emancipation was a means to end the war. In
The Wrong of Slavery, the Right of Emancipation, and the Future of the African Race in the United States, a report that Owen wrote in 1864, he also suggested that the Union should provide assistance to freedmen. ==Spiritualism==
