The Bill of Rights comprises the first ten amendments to the Constitution. Those amendments were adopted between 1789 and 1791, and all relate to limiting the power of the federal government. They were added in response to criticisms of the Constitution by the state ratification conventions and by prominent individuals such as Thomas Jefferson (who was not a delegate to the Constitutional Convention). These critics argued that without further restraints, the strong central government would become tyrannical. The amendments were proposed by Congress as part of a block of twelve in September 1789. By December 1791 a sufficient number of states had ratified ten of the twelve proposals, and the Bill of Rights became part of the Constitution. It is commonly understood that the Bill of Rights was not originally intended to apply to the states, though except where amendments refer specifically to the Federal Government or a branch thereof (as in the first amendment, under which some states in the early years of the nation officially established a religion), there is no such delineation in the text itself. Nevertheless, a general interpretation of inapplicability to the states remained until 1868, when the Fourteenth Amendment was passed, which stated, in part, that: No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. The Supreme Court has interpreted this clause to extend most, but not all, parts of the Bill of Rights to the states. Nevertheless, the balance of state and federal power has remained a battle in the Supreme Court. The amendments that became the Bill of Rights were actually the last ten of the twelve amendments proposed in 1789. The second of the twelve proposed amendments, regarding the compensation of members of Congress, remained unratified until 1992, when the legislatures of enough states finally approved it and, as a result, it became the Twenty-seventh Amendment despite more than two centuries of pendency. The first of the twelvestill technically pending before the state legislatures for ratificationpertains to the apportionment of the United States House of Representatives after each decennial census. The most recent state whose lawmakers are known to have ratified this proposal is Kentucky in 1792 during that commonwealth's first month of statehood.
