The New England Emigrant Aid Company[n 1] (originally the Massachusetts Emigrant Aid Company[4]) was a transportation company founded in Boston, Massachusetts[5] by activist Eli Thayer in the wake of the Kansas–Nebraska Act, which allowed the population of Kansas Territory to choose whether slavery would be legal. The company's ultimate purpose was to transport anti-slavery immigrants into the Kansas Territory. The company believed that if enough anti-slavery immigrants settled en masse in the newly-opened territory, they would be able to shift the balance of political power in the territory, which in turn would lead to Kansas becoming a free state (rather than a slave state) when it eventually joined the United States.[6][page needed]
The company is noted less for its direct impact than for the psychological impact it had on proslavery and abolitionist groups. Thayer's prediction that the company would eventually be able to send 20,000 immigrants a year never came to fruition, but it spurred border ruffians from nearby Missouri, where slavery was legal, to move to Kansas to ensure its admission to the Union as a slave state. That, in turn, further galvanized Free-Staters and other enemies of the Slave Power.[citation needed]
Thayer's intention was to capitalize on anti-slavery sentiment in the Northern United States and to send settlers to Kansas to purchase land and build houses, shops, and mills. They could then sell the land at a significant profit and send the proceeds back to Thayer and his investors. At the behest of several investors, who found the notion of profiting from the anti-slavery cause distasteful, the company's model was shifted to that of a benevolent society, and it was renamed the New England Emigrant Aid Company in 1855. While the company achieved neither a profit nor a significant impact on the population of Kansas, it played an important role in the events that would later be termed Bleeding Kansas.[citation needed]
