Eighteen Representatives had been elected in 1808, 16 Democratic-Republicans and 2 Federalists. One Democratic-Republican resigned and was replaced by another Representative from the same party, so that there was still a 16-2 division. Four of the Democratic-Republicans and two of the Federalists were "quids", a short-lived alliance of moderate Democratic-Republicans and Federalists. That was the last year in which the quids as a movement existed.

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:

Note: Many of these counties covered much larger areas than they do today, having since been divided into smaller counties

Election results


Fifteen incumbents (14 Democratic-Republicans and 1 Federalist) ran for re-election, of whom ten were re-elected. The incumbents John Ross (DR) of the 2nd district, Robert Jenkins (F) of the 3rd district and Matthias Richards (DR) also of the 3rd district did not run for re-election. Two seats changed from Federalist to Democratic-Republican control and one seat changed from Democratic-Republican to Federalist control, for a net loss of 1 seat by the Federalists. In the 1st district, there was a split between three "New School" and one "Old School" Democratic-Republicans, which split the Democratic-Republican vote enough to allow one of the three seats in that district to be won by a Federalist.
