- In April 1649, colonists voted into law An Act Concerning Religion (later known as the Maryland Toleration Act), which granted freedom of worship for all Christians. Although permanently repealed in 1692, the act was one of the first statutes granting religious liberty of any kind and was an important step toward true freedom of religion in the United States.
- In 1763, astronomer Charles Mason and surveyor Jeremiah Dixon were asked to resolve an 80-year land dispute between the Calvert family of Maryland and the Penn family of Pennsylvania by marking the correct boundary. The resulting Mason-Dixon Line took five years to complete and later became the demarcation between the free North and slave-holding South.
- On September 14, 1814, while witnessing the British bombard Fort McHenry in an attempt to capture Baltimore during the War of 1812, Francis Scott Key wrote the lyrics to “The Star-Spangled Banner.” In 1931, the United States adopted the song as its national anthem.
- Branded “The town that fooled the British,” St. Michaels avoided destruction by British invasion on August 10, 1813, when residents—forewarned of an imminent attack—turned off all their lights and attached lanterns to the masts of ships and the tops of trees, causing cannons to overshoot the town. The only house to be struck became known as the “Cannonball House.”
- The Battle of Antietam in Sharpsburg on September 17, 1862, was the first attack on Union soil during the Civil War and the bloodiest one-day battle in U.S. history with more than 23,000 soldiers killed. Although it ended in a draw, President Abraham Lincoln used General Robert E. Lee’s retreat to Virginia as an opportunity to issue his preliminary Emancipation Proclamation, warning seceded states to return to the Union before the end of the year or their slaves would be declared free.
