1. May Day protests: May 1 is historically associated with workers' rights and labor movements, and North Carolina has been no stranger to May Day protests. In 1937, workers at the American Tobacco Company in Durham staged a May Day strike to demand higher wages and better working conditions. The strike lasted for several weeks and resulted in clashes with police, but the workers ultimately received some concessions from the company.

2. Statehood: May 1 is also an important day for North Carolina's statehood. On May 1, 1776, the Mecklenburg Declaration of Independence was signed in Charlotte, declaring the state's independence from Great Britain. While the authenticity of this document is sometimes contested, it holds an important place in North Carolina's early history.

3. Civil War: The Battle of Chancellorsville, fought from April 30 to May 6, 1863, was a significant event in North Carolina's involvement in the Civil War. The Confederate Army, which included many North Carolina troops, won a decisive victory over Union forces, but suffered heavy casualties, including the loss of General Thomas "Stonewall" Jackson.

4. Education: On May 1, 1795, the University of North Carolina at Chapel Hill opened its doors to students, making it the first public university in the United States. Today, UNC Chapel Hill is one of the most prestigious universities in the country and is known for its strong academic programs and athletic achievements.

5. International Workers' Day: May 1 is also celebrated around the world as International Workers' Day, and North Carolina has seen its fair share of May Day celebrations over the years. In recent years, activists in Raleigh and other cities have organized protests and marches to demand better working conditions, immigrant rights, and other social justice issues. While the holiday is not officially recognized or celebrated by the state, it remains an important day for many workers and activists in North Carolina and beyond.
