The statement that accurately describes the terms of the Compromise of 1850 is:
"Popular sovereignty was established, allowing states to vote on whether or not to have slavery."
The Compromise of 1850 included provisions such as admitting California as a free state and allowing the territories of New Mexico and Utah to decide the issue of slavery based on popular sovereignty. Additionally, it included a stricter Fugitive Slave Act and addressed the status of slavery in the District of Columbia, but did not eliminate slavery there. Texas did not have the right to annex New Mexico; instead, Texas ceded some of its territory in exchange for debt relief.
