The Georgia Platform was a statement executed by a Georgia Convention in Milledgeville, Georgia on December 10, 1850, in response to the Compromise of 1850. Supported by Unionists, the document affirmed the acceptance of the Compromise as a final resolution of the sectional slavery issues while declaring that no further assaults on Southern rights by the North would be acceptable. The Platform had political significance throughout the South. In the short term it was an effective antidote to secession, but in the long run it contributed to sectional solidarity and the demise of the Second Party System in the South. Much of the document was written by Charles J. Jenkins, a Whig lawyer and state legislator from Augusta.

Sectional tensions over the issue of the westward expansion of slavery, previously resolved by the Missouri Compromise, were reawakened with the debate over Texas Annexation and the Mexican War. Texas Annexation was the major issue in the national elections of 1844, but, despite some signs of a sectional split, the election was resolved along the established party lines. Opposition to the Mexican War and, especially, opposition to acquiring new territory, also split largely along party lines.

It was only with the introduction of the Wilmot Proviso in August 1846 that the national debate began to split along sectional lines. During the "prolonged deadlock of 1846-50" the idea of secession as a possible solution to Northern threats against slavery began to take root among more and more Southerners. In December 1849 Congressman Alexander Stephens, the future vice-president of the Confederacy, wrote to his brother, "I find the feeling among the Southern members for a dissolution of the Union – if the antislavery [measures] should be pressed to extremity – is becoming more general than at first."

In the United States Congress the issues dividing North and South were debated ferociously, leading to the Compromise of 1850 that was intended to address all outstanding issues relating to slavery. After an early failure to pass a single omnibus bill, in September 1850 President Millard Fillmore signed the five separate bills that made up the compromise.

Around the same time, radicals within the South pursued their own solution, leading to the Nashville Convention in June 1850 that some hoped would become a secessionist convention. The convention denounced the proposed compromise, but rejected secession over any territorial restrictions on slavery in favor of extending the Missouri Compromise line to the west coast.

Secessionist strength was strongest in Mississippi, Alabama, Georgia, and South Carolina. In the first three of these states there arose local Union or Constitutional Parties to counter the radical Southern Rights parties which were forming. In South Carolina the Southern Rights agenda was already the dominant force in the state, and its leaders were already pressing the other states for secession. The new Union parties attracted the overwhelming majority of Whigs in the three states. In Alabama and Mississippi the Whigs had been weak, and the creation of the Union parties revitalized the opposition to the dominant state Democratic Parties.

In Alabama, the state divided along sectional lines. In the north of the state the pro-compromise Union Party had its greatest strength while Democrats in the south organized the Southern Rights Party.

In Mississippi, Governor John Quitman and Jefferson Davis led the Southern rights group, while Senator Henry S. Foote, who had lost status in the state over his support for the compromise, was the most visible face of the Union Party.
