It would be the marvelous Roman Empire
The fugitive slave act of 1793 authorized local governments to recapture escaped slaves and imposed laws restricting the aiding of runaway slaves. This act was provised in 1850 “compromise of 1850” forcing locals to aid in the capturing of slaves and denied the right of slaves to have a trial by jury. The aiding of escaped slaves was also punished more than in the first act
The South opposed the Wilmot Proviso because it would have prevented any new territories from having slavery in them.
In 1846, Congressman David Wilmot of Pennsylvania introduced the proviso as an amendment to an appropriations bill in connection with the peace treaty being negotiated with Mexico. His amendment stipulated that any territory gained from Mexico would be free, not allowing slavery. The specific language of the proviso went like this:
<span><em>Provided, That, as an express and fundamental condition to the acquisition of any territory from the Republic of Mexico by the United States, by virtue of any treaty which may be negotiated between them, and to the use by the Executive of the moneys herein appropriated, neither slavery nor involuntary servitude shall ever exist in any part of said territory, except for crime, whereof the party shall first be duly convicted</em>.

Wilmot's amendment passed in the House of Representatives, but was unable to get approval in the Senate. The high-intensity debate over slavery and the expansion of slavery was evidenced by how things went with the "Wilmot Proviso."
