The Compromise of 1850 was a package of five separate bills passed in the United States in September of that year. The third bill, popular sovereignty, was developed by Lewis Cass and Douglas as the eventual Democratic Party position, letting each territory decide whether to allow slavery.

He called it Popular Sovereignty
No most northerners did not like popular sovereignty because it violated the Missouri compromise. The South was in favor of popular sovereignty because it allowed the people to decide if slavery would be allowed in a new territory.
Stephen A. Douglas suggested dropping the Missouri compromise's ban on slavery. Instead, popular sovereignty (the vote of the residents) would decide the issue.
'Popular Sovereignty' was the term coined by Stephen Douglas for a local vote on slavery in each new state as it joined the Union. It was the basis of the Kansas-Nebraska Act, which was first tested - disastrously - when Kansas was admitted as free soil. This followed the unsuccessful Compromise of 1850, which did not involve Popular Sovereignty.

Under the Compromise of 1850, the territories that were able to choose by popular sovereignty whether or not to allow slavery were New Mexico and Utah. This compromise aimed to address the contentious issue of slavery in newly acquired territories following the Mexican-American War. Kansas and Nebraska later also adopted popular sovereignty through the Kansas-Nebraska Act of 1854, but they were not part of the Compromise of 1850 itself.
