The Royal Charter is the founding document of the College of William and Mary, issued on 8 February 1693. It gives the purpose of the new College as well as listing the original Board of Visitors. The original Charter given to the College of William and Mary was lost some time around the Revolutionary War, likely while the College was being used as a military hospital. Currently, the Special Collections Research Center has two contemporary copies of the Charter, including the copy that was likely given to Edmund Andros, Governor of Virginia from 1692 to 1698. You can find more information about the Royal Charter, including a transcription, in the Special Collections Research Center Wiki.
