Who was responsible for writing the Amendments that later became the Bill of Rights

The amendments that became the Bill of Rights were largely crafted by James Madison, who is often referred to as the "Father of the Bill of Rights." Madison played a pivotal role in drafting and advocating for the first ten amendments to the United States Constitution, which were meant to protect individual liberties and limit the power of the government.

Madison's proposals were influenced by earlier documents such as the Virginia Declaration of Rights, written by George Mason, as well as by the work of other Enlightenment thinkers and the input of many other figures of the time, including suggestions from several state ratification conventions during the debate over the original Constitution. After a process of consideration and revision by Congress, these amendments were submitted to the states for ratification and became part of the Constitution on December 15, 1791.
