May 20th, 1861, was chosen as the date for the state of North Carolina to secede from the Union. North Carolinians met at a convention on May 20, 1861, to declare themselves free from the United States government. They adopted this state flag on June 22, 1861, indicating a declaration of independence from the United States government on the 86th anniversary of Mecklenburg's supposed declaration of independence from the British government.
