Who succeeded and won the election over John Adams becoming Third President of the United States?

Thomas Jefferson succeeded John Adams as the Third President of the United States after winning the election of 1800. This election, often referred to as the "Revolution of 1800," marked a significant shift in the political landscape as it resulted in the first peaceful transfer of power between political parties in U.S. history, from the Federalists to the Democratic-Republicans. Jefferson's presidency is notable for the Louisiana Purchase in 1803, where the U.S. acquired a vast territory from France, effectively doubling the size of the nation. This pivotal event not only expanded the borders of the young country but also set the stage for westward expansion and the exploration of new frontiers, including the famous Lewis and Clark expedition.
