How did the federalist slide power during the Jefferson administration?

During the Jefferson administration, Federalists experienced a decline in power primarily due to Jefferson's policies and the rise of the Democratic-Republican Party, which advocated for a more agrarian and decentralized government. Jefferson's election in 1800 marked a significant shift, as he aimed to reduce the scope of federal authority, dismantle some Federalist initiatives, and promote states' rights. The Federalist Party further weakened due to internal divisions and their opposition to the War of 1812, eventually leading to their decline in national politics.
