Ten amendments make up the United States Bill of Rights, a constitutional milestone relevant to America250.
The Bill of Rights consists of Amendments One through Ten to the United States Constitution. Congress originally proposed twelve amendments on September 25, 1789. The states ratified Articles Three through Twelve on December 15, 1791; those became the first ten amendments.
The two proposals that did not initially become part of the Bill of Rights had different outcomes. The original Article One remains unratified, while the original Article Two was eventually ratified in 1992 as the Twenty-seventh Amendment. The Bill of Rights was shaped partly by Anti-Federalist concerns that the new Constitution needed explicit protections for individual liberties.
