The new government under President George Washington took office in New York in March 1789.[104] James Madison spearheaded Congressional amendments to the Constitution as assurances to those cautious about federal power, guaranteeing many of the inalienable rights that formed a foundation for the revolution, and Rhode Island was the final state to ratify the Constitution in 1791. ./cache/en-wikipedia-org-310.html ./txt/en-wikipedia-org-310.txt
