The correct answer is 1800.
Explanation: The election of 1800, sometimes referred to as the "1800 Revolution", was the presidential election between Federalist Party candidate John Adams, Democratic-Republican Party candidate Thomas Jefferson, and his running mate Aaron Burr. This election served as the first instance of the peaceful transfer of power from one party to the other and is therefore seen as a "revolution" without bloodshed or violence to prevent the transfer of power.
The political factions of the new country were still strong and campaigned strategically for their candidates during the 1800 election. This was the first royal election among political parties and the beginning of a process that is now commonplace in American politics.
