Eli Thayer: New England Emigrant Aid Company founder and Free-State organizer

Background and the Kansas crisis

When Congress enacted the Kansas–Nebraska Act in 1854, it allowed the settlers of the new territories to decide by popular vote whether slavery would be permitted. The law set off a rush of migration to the Kansas Territory: pro-slavery advocates, northern abolitionists and other anti-slavery migrants all sought to influence the outcome. The competition for settlers and political control produced episodes of violence and intimidation that historians refer to as Bleeding Kansas.

New England Emigrant Aid Company

Thayer established the New England Emigrant Aid Company to encourage and assist anti-slavery settlers to move to Kansas. The organization promoted settlement by arranging transportation and supplies for those who supported keeping Kansas free of slavery. Its goal was to increase the number of Free-Staters in the territory so that, when voting occurred, the balance would favor a free state.

Public office and later life

In addition to his organizing work, Thayer served in elected office as a legislator and was a member of the United States House of Representatives from 1857 until 1861. After his congressional service he pursued business interests and civic activities in Massachusetts. Throughout his career he remained identified with efforts to shape settlement patterns and public policy in the new territories, a strategy intended to influence whether slavery would expand westward.

Assessment and death

Thayer is most widely remembered for founding the New England Emigrant Aid Company and for his role during the struggle over Kansas's future. He died in Worcester, Massachusetts on April 15, 1899. His initiatives are often cited in discussions of how organized migration and private associations affected sectional politics in the 1850s, and how those activities contributed to the tensions that preceded the Civil War.

During the Kansas crisis, the arrival and settlement of both Free-Staters and pro-slavery migrants helped determine the political character of the territory, illustrating how migration, organization, and local voting were tied together in mid-19th-century American politics.
