This Day in History

On March 23, 1867, Congress overrode President Andrew Johnson’s veto to pass the Second Reconstruction Act, strengthening federal authority in the South. The law advanced voting rights for African American men and reshaped post–Civil War governance, marking a pivotal moment in the nation’s struggle to define freedom, citizenship, and equality.

On March 22, 1903, the Anthracite Coal Commission delivered a landmark compromise after the 1902 coal strike. Backed by President Theodore Roosevelt, it granted miners higher wages and shorter hours while preserving an open shop, marking a pivotal moment in federal involvement in labor disputes and industrial reform in America.

On March 20, 1774, Britain passed the Boston Port Act, closing Boston Harbor after the Tea Party. The harsh punishment devastated the local economy but united the colonies in resistance. Instead of restoring order, the act fueled outrage, strengthened cooperation, and pushed America closer to revolution and independence.

On March 20, 1800, Alessandro Volta introduced the first electric battery, the voltaic pile, providing a steady source of electrical current. This breakthrough transformed electricity from a scientific curiosity into a practical tool, laying the foundation for modern technology, electrochemistry, and countless innovations that continue to power the world today.

On March 19, 1918, President Woodrow Wilson signed the Standard Time Act, establishing Daylight Saving Time and formalizing U.S. time zones under federal control. The law brought consistency to timekeeping, improved coordination across industries, and reflected the nation’s shift toward efficiency during World War I and an increasingly modern era.
