The Constitution of the Commonwealth of Virginia is the document that defines and limits the powers of the state government and the basic rights of the citizens of the U.S. Commonwealth of Virginia. Like all other state constitutions, it is supreme over Virginia's laws and acts of government, though it may be superseded by the United States Constitution and U.S. federal law as per the Supremacy Clause.
The original Virginia Constitution of 1776 was enacted in conjunction with the Declaration of Independence by the first thirteen states of the United States of America. Virginia was an early state to adopt its own Constitution on June 29, 1776, and the document was widely influential both in the United States and abroad. In addition to frequent amendments, there have been six major subsequent revisions of the constitution (by Conventions for the constitutions of 1830, 1851, 1864, 1870, 1902, and by commission for 1971 amendments). These new constitutions have been part of, and in reaction to, periods of major regional or social upheaval in Virginia. For instance, the 1902 constitution included provisions to disfranchise African Americans, who in 1900 made up nearly 36% of the state's population. They did not regain suffrage until after passage of federal civil rights legislation in the mid-1960s.
The preparation of the first Virginia Constitution began in early 1776, in the midst of the early events of the American Revolution. Among those who drafted the 1776 Constitution were George Mason and James Madison. Thomas Jefferson was Virginia's representative to the Second Continental Congress in Philadelphia at the time, and his drafts of the Virginia constitution arrived too late to be incorporated into the final document. James Madison's work on the Virginia Constitution helped him develop the ideas and skills that he would later use as one of the main architects of the United States Constitution.
