Origin: Colonial naval-stores industry (tar, pitch, turpentine) from vast longleaf pine forests. Workers barefoot in tar kilns → "tar heels." Civil War legend: NC troops stood firm while others fled — "God bless the Tar Heels!" — General Lee (apocryphal). Adopted proudly.
Origin: Sabal palmetto (cabbage palm), state tree. 1776 Battle of Sullivan’s Island: Fort Moultrie’s palmetto-log walls absorbed British cannonballs, saving Charleston. Palmetto became symbol of resilience; on state flag (1861) and seal.
