Elections to the United States House of Representatives were held in Pennsylvania on October 14, 1806, for the 10th Congress.
Background In the previous elections, 17 Democratic-Republicans and 1 Federalist had been elected to represent Pennsylvania. There were two subsequent special elections which did not result in any seats changing parties. One seat held by a Democratic-Republican had become vacant and was not yet filled at the time of the election.
As in the previous election, there was a breakaway faction of the Democratic-Republican Party allied with the Federalists known as the tertium quids or Constitutional Republicans, which ran candidates in several districts. Several of the elected quids aligned with the Federalists on the federal level.
Congressional districts Pennsylvania was divided into 11 districts, of which four were plural districts with 11 Representatives between them, with the remaining 7 Representatives elected from single-member districts. The districts were: The (3 seats) consisted of Delaware and Philadelphia counties (including the City of Philadelphia) The (3 seats) consisted of Bucks, Luzerne, Montgomery, Northampton, and Wayne Counties The (3 seats) consisted of Berks, Chester, and Lancaster Counties The (2 seats) consisted of Cumberland, Dauphin, Huntingdon, and Mifflin Counties The consisted of Centre, Clearfield, Lycoming, McKean, Northumberland, Potter, and Tioga Counties The consisted of Adams and York Counties The consisted of Bedford and Franklin Counties The consisted of Armstrong, Cambria, Indiana, Jefferson, Somerset, and Westmoreland Counties The consisted of Fayette and Greene Counties The consisted of Washington County The consisted of Allegheny, Beaver, Butler, Crawford, Erie, Mercer, Venango, and Warren Counties
Note: Many of these counties covered much larger areas than they do today, having since been divided into smaller counties
