2. Look for events that had a significant and long-lasting impact on the world, particularly events that shaped the course of history.
3. Consider events that were catalysts for change, such as wars, revolutions, technological advancements, or important legislation.

Regarding the U.S. presidents who served during this period and the order in which they held office, here are the three presidents:

1. Thomas Jefferson (1801-1809) - He was the third president of the United States and is known for the Louisiana Purchase, the Lewis and Clark expedition, and the Embargo Act of 1807.
2. James Madison (1809-1817) - He was the fourth president and played a crucial role during the War of 1812, including the writing of the U.S. Constitution and the Bill of Rights.
3. James Monroe (1817-1825) - He was the fifth president and is best known for the Monroe Doctrine, which asserted U.S. opposition to European colonization efforts in the Americas.
