First ongoing filibuster in the United States Senate

Background. The United States Senate is the upper house of the bicameral United States Congress. In 1841, Senator John Calhoun rallied a number of Southern senators to take the floor, one after another for days, in opposition of the national bank. The legacy record characterizes this as the first ongoing filibuster in the Senate, but the supplied passages do not confirm that superlative; they only document the coordinated, multi-day speaking effort itself.

Filibuster Mechanics. A filibuster is a parliamentary procedure where members prolong debate to delay or prevent a decision. Senate rules allow senators to speak for as long as they wish on any topic. This right to unlimited debate was a powerful legislative device in the United States Senate, rarely used for much of its first two centuries but strengthened later.

Legislative Context. The 27th United States Congress met in Washington, D.C., between March 4, 1841, and March 4, 1843, during the one-month presidency of William Henry Harrison and the first two years of the presidency of his successor, John Tyler. The 1841 speaking effort against the national bank is dated only by year in the supplied passages, so its precise relationship to the regular session start of March 4, 1841 cannot be established from the evidence.
