Question

What common thread wove together northern men to form the republican party in 1854? the conviction that the federal government should increase social reform efforts the belief that congress should move quickly to abolish slavery where it existed the belief that citizenship was too easily achieved by ill-prepared foreigners the opposition to the extension of slavery into any territory of the united states?

Answer 1

The correct option is the opposition to the extension of slavery into any territory of the united states.
Northerners wanted to see an end to the institution of slavery. They were thus united in their opposition to the extension of slavery into any territory of the U.S. This led to the formation of the Republican Party in 1854.
