When the Quasi-War with France threatened to escalate in 1798, Congress raised a large army and enlarged the navy. To pay for it, Congress in July 1798 imposed $2 million in new taxes on real estate and slaves, apportioned among the states according to the requirements of the Constitution. It was the first such federal tax. Congress had also recently passed the Alien and Sedition Acts, criminalizing dissent and increasing the power of the executive branch under John Adams.
Beginning
In July 1798, during the troubles between the United States and France now known as the Quasi-War, the US Congress levied a direct tax of $2 million, of which Pennsylvania was called upon to contribute $237,000. There were very few slaves in Pennsylvania, and the tax was accordingly assessed upon dwelling-houses and land, the value of the houses being determined by the number and size of the windows. The inquisitorial nature of the proceedings, with assessors riding around and counting windows, aroused strong opposition, and many refused to pay, making the constitutional argument that this tax was not being levied in proportion to population. Pennsylvania auctioneerJohn Fries organized meetings, starting in February 1799, to discuss a collective response to the tax. As an itinerant auctioneer, Fries was well acquainted with the German-Americans issues in the southeastern part of Pennsylvania. Many advocated resistance in response to the tax. In Milford township, particularly, assessors were unsuccessful in completing their tax assessments due to intimidation. At a meeting called by government representatives in an attempt to explain the tax in a way as to defuse tensions, protesters waving liberty flags, some armed and in Continental Army uniforms, shouted them down and turned the meeting into a protest rally. The assessors at first determined to continue their work in Milford. Fries personally warned the assessors to quit their work, but they ignored the threat. He then led a small armed band that harassed the assessors enough that they decided to abandon Milford for the time being. In early March, a local militia company and a growing force of armed irregulars met, marching to the accompaniment of drum and fife. About a hundred set off for Quakertown in pursuit of the assessors, whom they intended to place under arrest. They captured a number of assessors there, releasing them with a warning not to return and to tell the government what had happened to them.
Spread
Opposition to the tax spread to other parts of Pennsylvania. In Penn, the appointed assessor resigned under public threats; the assessors in Hamilton and Northampton also begged to resign, but were refused as nobody else could be found to take their places. Federal warrants were issued, and the U.S. Marshal began arresting people for tax resistance in Northampton. Arrests were made without much incident until the marshal reached Macungie, then known as Millerstown, where a crowd formed to protect a man from arrest. Failing to make that arrest, the marshal made a few others and returned to Bethlehem with his prisoners. Two separate groups of rebels independently vowed to liberate the prisoners, and marched on Bethlehem. They prevailed without violence, and freed the tax resisters who had been arrested. In response to this action, President John Adams called out a force of federal troops and local militia. They marched into the rebellious counties and began making wholesale arrests of the insurgents. John Fries was among the men captured.
Trials
Thirty men went on trial in Federal court. Fries and two others were tried for treason and, with Federalists stirring up a frenzy, were sentenced to be hanged. President John Adams pardoned Fries and others convicted of treason. Adams was prompted by the narrower constitutional definition of treason, and he later added that the rebels were "as ignorant of our language as they were of our laws" and were being used by "great men" in the opposition party. He issued a general amnesty for everyone involved on May 21, 1800. Historians are agreed that the Federalists overreacted and mishandled a small episode. The long-term impact was that the German-American communities rejected the Federalist Party.
