1. On September 9, 1777, the Battle of Brandywine was fought during the American Revolutionary War. This battle is significant for West Virginia history because it was fought in southeastern Pennsylvania, where many soldiers from Virginia, including West Virginia before it became a separate state, fought against the British Army as part of the Continental Army.

2. September 9, 1862, was the day that Confederate General Robert E. Lee led his army across the Potomac River into Maryland, beginning what would be known as the Maryland Campaign during the American Civil War. West Virginia played a crucial role in this campaign, as Union forces from the state fought against Lee's army at the Battle of Antietam.

3. On September 9, 1893, the West Virginia State Capitol Building was dedicated in Charleston, the state's capital. The building is still in use today and is listed on the National Register of Historic Places.

4. September 9, 1950, marked the first day of classes at West Virginia State College (now West Virginia State University) after it was desegregated. The college, located in Institute, West Virginia, was one of the first historically Black colleges and universities in the United States to integrate.

5. On September 9, 1972, the West Virginia University football team defeated the University of North Carolina in a game that is now known as the "Backyard Brawl." The rivalry between the two teams, which are only a few hours apart, is one of the oldest and most intense in college football.
