James Madison Writings and Biography. Site about the founding fathers offers a biography of President Madison, his portraits, and a collection of his writings.
From the site:
The oldest of 10 children and a scion of the planter aristocracy, Madison was born in 1751 at Port Conway, King George County, VA, while his mother was visiting her parents. In a few weeks she journeyed back with her newborn son to Montpelier estate, in Orange County, which became his lifelong home. He received his early education from his mother, from tutors, and at a private school. An excellent scholar though frail and sickly in his youth, in 1771 he graduated from the College of New Jersey (later Princeton), where he demonstrated special interest in government and the law. But, considering the ministry for a career, he stayed on for a year of postgraduate study in theology.
Back at Montpelier, still undecided on a profession, Madison soon embraced the patriot cause, and state and local politics absorbed much of his time. In 1775 he served on the Orange County committee of safety; the next year at the Virginia convention, which, besides advocating various Revolutionary steps, framed the Virginia constitution; in 1776-77 in the House of Delegates; and in 1778-80 in the Council of State. His ill health precluded any military service.
In 1780 Madison was chosen to represent Virginia in the Continental Congress (1780-83 and 1786-88). Although originally the youngest delegate, he played a major role in the deliberations of that body. Meantime, in the years 1784-86, he had again sat in the Virginia House of Delegates. He was a guiding force behind the Mount Vernon Conference (1785), attended the Annapolis Convention (1786), and was otherwise highly instrumental in the convening of the Constitutional Convention in 1787. He had also written extensively about deficiencies in the Articles of Confederation.
