ConstitutionFacts.com states that James Madison originally proposed the Bill of Rights because some of the founding fathers argued that the U.S. Constitution did not protect human rights. Key influences in this proposal include the Virginia Declaration of Rights, the English Declaration of Rights and works of the Age of Enlightenment.
ConstitutionFacts.com also states that there were originally twelve amendments proposed in the bill of Rights, instead of the accepted ten. One of the rejected amendments dealt with the amount and distribution of representatives in congress. The other rejected amendment limited how much congress was able to increase the pay of its employees. This amendment was later ratified centuries later as the twenty-seventh amendment. These two amendments were supposedly dismissed because they had little to do with "rights", despite being included in a document called the Bill of Rights. The Bill of Rights is considered to have held a vital role in shaping the United States into a respectable nation.
