US Bill of Right's 1.7.1966

The stamp on this cover issued on 1.7.1966 at Miami Beach, FL commemorates the 175th anniversary of the Bill of Rights (the first ten amendments to the constitution) that established freedom of religion and speech, freedom of the press, the right to a jury trial and other safeguards to human rights.

The Bill of Rights is the collective name for the first ten amendments to the United States Constitution. Proposed to assuage the fears of Anti-Federalists who had opposed Constitutional ratification, these amendments guarantee a number of personal freedoms, limit the government's power in judicial and other proceedings, and reserve some powers to the states and the public. While originally the amendments applied only to the federal government, most of their provisions have since been applied to the states by way of the Fourteenth Amendment, a process known as incorporation.

The amendments were introduced by James Madison to the 1st United States Congress as a series of legislative articles. They were adopted by the House of Representatives on August 21, 1789, formally proposed by joint resolution of Congress on September 25, 1789, and came into effect as Constitutional Amendments on December 15, 1791, through the process of ratification by three-fourths of the states. While twelve amendments were proposed by Congress, only ten were originally ratified by the states. Of the remaining two, one was adopted 203 years later as the Twenty-seventh Amendment, and the other technically remains pending before the states.

The Bill of Rights enumerates freedoms not explicitly indicated in the main body of the Constitution, such as freedom of religion, freedom of speech, a free press, and free assembly; the right to keep and bear arms; freedom from unreasonable search and seizure, security in personal effects, and freedom from warrants issued without probable cause; indictment by a grand jury for any capital or "infamous crime"; guarantee of a speedy, public trial with an impartial jury; and prohibition of double jeopardy. In addition, the Bill of Rights reserves for the people any rights not specifically mentioned in the Constitution and reserves all powers not specifically granted to the federal government to the people or the States. The Bill was influenced by George Mason's 1776 Virginia Declaration of Rights, the English Bill of Rights 1689, and earlier English political documents such as Magna Carta (1215).

The Bill of Rights had little judicial impact for the first 150 years of its existence, but was the basis for many Supreme Court decisions of the 20th and 21st centuries. One of the first fourteen copies of the Bill of Rights is on public display at the National Archives in Washington, D.C.
