Final answer:
The Compromise of 1850 involved California, Texas, and the New Mexico Territory. While California was admitted as a free state, Texas had its border defined and gave up its claims beyond the Rio Grande for financial compensation, the New Mexico Territory used 'popular sovereignty' to decide on slavery.
Step-by-step explanation:
The Compromise of 1850 was a series of bills passed in the U.S. Congress aiming to resolve disputes over the status of slavery in the territory gained during the Mexican-American War (1846–1848). Specifically, the states that figured prominently in the Compromise of 1850 were California, Texas, and the New Mexico Territory. California was admitted as a free state, while Texas had its state border defined, and it received financial compensation for relinquishing its claims up to the Rio Grande. The New Mexico Territory used the principle of 'popular sovereignty' for deciding the status of slavery.
