1800 United States presidential election
The United States presidential election of 1800 was the fourth American presidential election between Thomas Jefferson and John Adams. Adams and Jefferson had awkwardly worked as president and vice president together for the previous four years, and it was a rematch of the 1796 election. In the end, Jefferson beat Adams and the long streak of Democratic-Republican presidents began. This election is referred to as the "Revolution of 1800" because it changed American politics a lot.
