““The Compromise of 1850 was authored by the legendary Whig politician Henry Clay. In addition to admitting California to the Union as a free state to balance with Texas, it allowed Utah and New Mexico to decide the issue of slavery on the basis of what became known as “popular sovereignty”, which meant the settlers could vote on whether their state should be a free state or slave state. Though a Whig proposed popular sovereignty in 1850, popular sovereignty as an idea would come to be championed by and associated with Democratic Illinois Senator Stephen Douglas. The Compromise also abolished the slave trade – though not the existence of slavery itself – in Washington, D.C.””
