Explain the Compromise of 1850 and why the entry of California into the Union was so contentious.
The Compromise of 1850, proposed by Senator Henry Clay of Kansas, was legislation designed to please both the Northern states and the Southern states. The North benefited from the Compromise because it admitted California as a free state, ended slave trading in the District of Columbia, and ended Texas' claim to New Mexico. The South benefited from the Compromise because it allowed New Mexico and Utah to decide whether they wanted slaves, D.C. residents could keep existing slaves, and enabled a more strict Fugitive Slave Act to be passed.
By 1848, California had over 100,000 residents, due largely to the discovery of gold at Sutter's Mill. The population qualified them for statehood; however, California's entry into the Union was contentious because its statehood would upset the balance of free states and slave states (15/15).
