Why was the compromise of 1850 needed

The Compromise of 1850 was made to stop the disputes over slavery in new territories added to the United States in the wake of the Mexican-American War. It admitted California as a free state, left Utah and New Mexico to decide for themselves whether to be a slave state or a free state, defined a new Texas-New Mexico boundary, and made it easier for slave owners to recover runways under the Fugitive Slave Act of 1850.

one of the major compromises in the constitutional convention was between the small states and big states. the small states wanted each state to have the same number of representatives in congress. the big states wanted representation based on population.
