1. Virginia is nicknamed the "Mother of Presidents" because eight U.S. presidents were born there, including the fifth president, James Monroe. On March 15, 1758, Monroe was elected to the Virginia House of Burgesses, the legislative body of the Virginia Colony.

2. On March 15, 1781, the American Revolutionary War was raging in Virginia. British forces, led by General Benedict Arnold, captured the town of Richmond, the capital of Virginia at the time. This was a major setback for the American forces, but they would eventually win the war with the help of France.

3. Many key battles of the American Civil War were fought in Virginia. On March 15, 1862, the Battle of Hampton Roads took place in Virginia waters. This was the first battle between ironclad warships, the USS Monitor and the CSS Virginia (formerly the USS Merrimack). The battle ended in a draw, but it marked a turning point in naval warfare.

4. Virginia has a long history of supporting education. On March 15, 1870, the Virginia state legislature passed an act to provide for the education of all children in the state, regardless of race. This was a significant step towards desegregation in Virginia and helped pave the way for the landmark Brown v. Board of Education Supreme Court decision in 1954.

5. Virginia is home to many historic sites and landmarks. On March 15, 1939, the historic Mount Vernon estate, which was George Washington's Virginia home, was designated a National Historic Site by the U.S. government. Today, Mount Vernon is a popular tourist destination and a symbol of Virginia's rich history.
