Congress passed the first federal internal revenue tax—an excise on distilled spirits (often called the “whiskey tax”)—as part of the Hamiltonian fiscal program to raise revenue and bolster federal authority. The measure quickly drew resistance in western Pennsylvania and other frontier regions where whiskey functioned as a key market commodity.
Local opposition to the excise coalesced in western Pennsylvania, where meetings and committees formed to coordinate resistance, intimidate would-be cooperators, and pressure federal officials. The Pittsburgh Assembly became an early focal point for organized protest.
Congress enacted the Militia Act empowering the president, under specified conditions, to call forth state militias when federal law could not be executed by ordinary judicial means—authority that would be invoked during the Whiskey Rebellion response.
Armed opponents of the excise confronted federal enforcement at Gen. John Neville’s Bower Hill estate. Fighting erupted as militants sought to stop service of process and intimidate officials, marking a sharp escalation from protest into armed resistance.
Hundreds of rebels surrounded Bower Hill; combat led to the death of rebel leader James McFarland, and Neville’s buildings were pillaged and burned. The episode became the rebellion’s most notorious violent flashpoint and spurred wider mobilization.
In the wake of the Bower Hill attack, large meetings drew both radicals and moderates; figures such as Hugh Henry Brackenridge argued that prior actions risked treason charges and urged pursuing negotiations or amnesty rather than further violence.
A band associated with David Bradford intercepted the U.S. mail leaving Pittsburgh, seeking letters that condemned the resistance. The act intensified federal alarm and helped trigger broader calls for a mass militia-style assembly.
An estimated 7,000 men assembled at Braddock’s Field near Pittsburgh, with some leaders discussing coercion of local elites and more expansive political aims. The gathering signaled the movement’s capacity for mass mobilization and raised fears of a march on Pittsburgh.
President George Washington issued a proclamation commanding insurgents to disperse and warning against aiding resistance, setting a deadline (September 1) and laying groundwork for escalation under statutory militia authority if defiance continued.
Delegates from multiple western counties met at Parkinson’s Ferry (later known as Whiskey Point) to debate resolutions and strategy. The convention appointed a committee to engage federal peace commissioners, with Albert Gallatin and others pressing for a peaceful settlement.
With negotiations failing to secure compliance, Washington issued another proclamation amid militia preparations, reinforcing federal determination to execute the law and signaling that military force would be used if necessary.
Washington called out roughly 13,000 militia from multiple states and moved toward western Pennsylvania. The show of force proved decisive: organized resistance dissolved, many leaders fled or went into hiding, and no pitched battle occurred.
As troops occupied the region, federal forces conducted coordinated arrests of suspected participants and witnesses. About 150 people were taken into custody in the crackdown that locals later remembered as a traumatic episode.
After subsequent prosecutions, only two men—Philip Wigle and John Mitchell—were convicted of treason. Washington pardoned them, pairing federal resolve to enforce law with clemency once the authority of the national government had been demonstrated.
