One of the most sacred rights of freemen is the right to petition for redress of grievances. In the old colonial days the British Parliament had refused even to listen to petitions presented by the colonists. But the First Amendment to the Constitution forbade Congress to make any law to prevent citizens of the United States from petitioning. John Quincy Adams, once President, was now a member of the House of Representatives. In 1836 he presented petition after petition, praying Congress to forbid slavery in the District of Columbia. Southerners, like Calhoun, thought these petitions were insulting to Southern slaveholders. Congress could not prevent the antislavery people petitioning. They could prevent the petitions being read when presented. This they did by passing "gag-resolutions." Adams protested against these resolutions as an infringement on the rights of his constituents. But the resolutions were passed. Petitions now came pouring into Congress. Adams even presented one from some negro slaves.

All these happenings brought about a great change of sentiment in the North. Many people, who cared little about negro slaves, cared a great deal about the freedom of the press and the right of petition. Many of these did not sympathize with the abolitionists, but they wished that some limit might be set to the extension of slavery. At the same time the Southerners were uniting to resist all attempts to interfere with slavery. They were even determined to add new slave territory to the United States.
