The current Constitution of the Commonwealth of Pennsylvania, most recently revised in 1968, forms the law for the United States Commonwealth of Pennsylvania. Although considered a new document, it is heavily based on the previous Constitution of 1874, and is often considered a revision of the earlier version.
The state constitution may only be amended after a majority vote of two consecutive sessions of the General Assembly and an affirmative vote by the electorate. Emergency amendments are permitted by a vote of two-thirds of the General Assembly and an affirmative vote by the electorate within one month.
Pennsylvania has had five constitutions since independence: 1776, 1790, 1838, 1874, and 1968. Prior to that, the province of Pennsylvania was governed for a century by a Frame of Government, of which there were four versions: 1682, 1683, 1696, and 1701.
