Why did the Emigrant Aid Society sneak voters into Kansas?

The Emigrant Aid Society, which aimed to promote anti-slavery settlement in Kansas, sneaked voters into the territory to influence its status as a free or slave state. By increasing the number of anti-slavery settlers, they sought to counter pro-slavery forces and ensure Kansas would enter the Union as a free state. This tactic was part of a broader conflict known as "Bleeding Kansas," where violent confrontations arose over the issue of slavery in the new territories. Ultimately, this strategy reflected the intense national divisions over slavery during the mid-19th century.
