Today in US history on February 25: Thomas Jefferson secures nomination, Samuel Colt patents the revolver, and the US dollar enters circulation

From battlefield victories and presidential politics to technological breakthroughs and moments of deep moral contradiction, this day in US history captures the forces that have repeatedly shaped the American story. It was a date marked by military resolve on the western frontier, political consolidation in the early republic, innovations that would alter daily life and warfare, and social realities that exposed the nation’s unresolved injustices.

In 1779, during the American Revolutionary War, George Rogers Clark accepted the unconditional surrender of British Lieutenant Governor Henry Hamilton at Fort Sackville, securing a strategic victory for American forces in the western frontier. The capture of the fort at Vincennes strengthened US claims to the Northwest Territory and weakened British influence in the region.

Political history was also made in 1804 when Thomas Jefferson was nominated for a second term as President of the United States by the Democratic-Republican caucus, setting the stage for his re-election and the continuation of his vision for the young republic.


Innovation and controversy marked the year 1836. Inventor Samuel Colt patented the first practical revolving-cylinder, multi-shot revolver, an invention that would transform firearms and warfare. That same year, showman P. T. Barnum sparked outrage by exhibiting enslaved African American woman Joice Heth, falsely claiming she was 161 years old and had been George Washington’s nursemaid, an episode later remembered as one of the darkest chapters of early American entertainment.

Economic and political milestones followed in later decades. In 1862, the United States Congress passed the First Legal Tender Act, authorizing the issuance of the United States note, or “greenback,” marking the country’s first use of fiat paper money as legal tender. In 1870, Hiram R. Revels was sworn in as the first African American member of Congress, representing Mississippi in the U.S. Senate, a landmark moment in American political history during the Reconstruction era.

Together, these events reflect the complexity of the American past, shaped by military struggle, democratic evolution, technological change, and ongoing battles over justice and equality.
