The admission of a state as a free state or a slave state had a significant impact on the balance of power between free states and slave states in the United States. The admission of a free state would upset the balance of power in favor of the free states, while the admission of a slave state would maintain the balance of power in favor of the slave states. This was a major issue leading up to the American Civil War, as the North and South were divided over the issue of slavery and the admission of new states as either free or slave states. The admission of free states also had an impact on the expansion of slavery into new territories, as free states would be less likely to allow slavery to expand into those territories.
