1. On March 15, 1781, the Battle of Guilford Court House took place in present-day Greensboro, North Carolina. It was a pivotal battle in the Southern theater of the Revolutionary War, with British forces led by General Charles Cornwallis engaging Continental Army troops led by General Nathanael Greene. Although the British technically won the battle, they suffered heavy losses and were unable to capitalize on their victory. The battle is widely considered a turning point in the war and a precursor to the eventual American victory at Yorktown.

2. On March 15, 1820, the University of North Carolina at Chapel Hill was officially chartered by the North Carolina General Assembly. The university, the oldest public university in the United States, had been established ten years earlier with the help of William R. Davie and other prominent North Carolinians. Today, UNC-Chapel Hill is one of the top public universities in the country, known for its strong academics, research programs, and athletic teams.

3. On March 15, 1936, the Great Smoky Mountains National Park was officially dedicated. The park, which straddles the North Carolina-Tennessee border, is one of the most biodiverse areas in the country and contains a wide variety of plant and animal species. It is also home to the famous Appalachian Trail and numerous hiking trails, campgrounds, and scenic overlooks.

4. On March 15, 1960, the Sit-In movement arrived in North Carolina when four students from North Carolina A&T State University in Greensboro sat down at a segregated lunch counter in a Woolworth's store in downtown Greensboro. The students, later known as the Greensboro Four, were protesting segregation and discrimination in public spaces. Their act of civil disobedience sparked similar protests across the country and helped to galvanize the civil rights movement.

5. On March 15, 2017, Governor Roy Cooper signed House Bill 142, which repealed the controversial and discriminatory North Carolina House Bill 2. HB2 had been widely criticized for its restrictions on bathroom access for transgender individuals and its nullification of local laws protecting LGBT individuals from discrimination. The repeal of HB2 was seen as a positive step forward for civil rights and human dignity in North Carolina.
