A connection between northern democrats free soilers and conscience Whigs in 1854 was that they formed the Republican party.
Anti-slavery Whigs organized meetings in the upper midwestern states to explain the production of a new party. One of the meeting which took place in Wisconsin on March 20, 1854, is usually recognized as the founding meeting of the Republican Party. The Democrats and Whigs were clearly distributed over the slavery issue, and their power efforts paved the way to create a new political party, the Republican Party, which was established in 1854 and remained united in their decision to stop the spread of slavery into the territories and defend the Union.
