James Madison [SEP] Introduction
After the ratification of the Constitution, Madison emerged as an important leader in the United States House of Representatives and served as a close adviser to President George Washington. He was the main force behind the ratification of the United States Bill of Rights, which enshrines guarantees of personal freedoms and rights within the Constitution. During the early 1790s, Madison opposed the economic program and the accompanying centralization of power favored by Secretary of the Treasury Alexander Hamilton. Along with Thomas Jefferson, Madison organized the Democratic-Republican Party, which was, alongside Hamilton's Federalist Party, one of the nation's first major political parties.
