The Mecklenburg Declaration of Independence, also known as the MeckDec, was a document drafted and signed on May 20, 1775 in Charlotte, North Carolina. This declaration was the first in the American colonies to call for complete independence from British rule, a year before the famous Declaration of Independence was signed. This document was a result of growing tensions between the American colonists and the British government, as well as the influence of Enlightenment ideas on the colonists.

The MeckDec asserted the rights of the colonists to govern themselves and to break away from British control. It also stated the grievances against the British and their violation of the colonists' natural rights. Although the exact wording of the original document has been disputed and lost over time, its significance as a precursor to the Declaration of Independence cannot be denied.

Today, the Mecklenburg Declaration of Independence is celebrated as a symbol of American independence and serves as a reminder of the bravery and determination of the early colonists in their fight for freedom.
