How did the Federalists lose power during the Jefferson administration?
The federalists lost power because of westward expansion. With more people moving to the west there were more people who supported Thomas Jefferson and his pro-agrarain ways. (agrarianism is the belief that rural farming communities are morally superior to city-communities). People supporting Thomas Jefferson supported the Democratic - Republicans, and this led to a drop in the support of the Federalists. Also included in this is the fact that Thomas Jefferson was the first president to live in the new capitol Washington, DC. which was between the southern states of Virginia and Maryland. This marked the beginning to the Federalist decline, as the Federalists were centered in the northern New England areas.
Also Arron Burr (VP) shot and killed a main Federalist Hamilton in a duel.
