Written by George Mason (1725-1792), who Thomas Jefferson regarded as the “the wisest man of his generation,” the Virginia Declaration of Rights was adopted by the Virginia Constitutional Convention on June 12, 1776. Widely copied by the other colonies (by the end of 1776 five colonies had adopted declarations of rights; by 1783 every state had some form of a bill of rights), it became the basis of the Bill of Rights to the U.S. Constitution after Mason fought against ratification of the Constitution because it contained no bill of rights. The Declaration of Rights was also used by Thomas Jefferson for the opening paragraphs of the Declaration of Independence. The Marquis de Condorcet called the Virginia Declaration of Rights “the first Bill of Rights to merit the name.”
