gag rule

A legislative device, adopted by the US House of Representatives from May 1836 to December 1844, prohibiting discussion or debate of antislavery petitions. During this eight-year period, the petitions sent to Congress numbered into the thousands and were signed by more than 2 million supporters of the abolitionist movement. All were blocked from review.

The southern congressman Henry Laurens Pinckney, representing South Carolina, initiated the gag rule on parliamentary procedure. It was held in place and renewed yearly by proslavery representatives, mainly from the South, who disapproved of any discussion of slavery; and antislavery northerners, who supported abolition but saw the rule as a peacekeeping measure and did not wish to antagonize the South. Former US president John Quincy Adams, who was representing Massachusetts in Congress at this time, strongly supported abolitionism and pioneered the effort to bring an end to the gag rule, arguing that it infringed upon citizens' constitutional right to petition. The rule was repealed in December 1844.

Although the gag rule halted congressional debate for nearly a decade, it ultimately aided in the abolitionist movement. Warnings from the American Anti-Slavery Society had already been sent throughout the nation that the swelling power of slave states would eventually nullify all US liberties. Citizens (even from the proslavery camp) were quick to support the abolitionist movement in order to prevent their liberties from being violated.
