Monroe fell out with his longtime friend James Madison after Madison rejected the Monroe–Pinkney Treaty that Monroe negotiated with Britain. He unsuccessfully challenged Madison in the 1808 presidential election, but in April 1811 he joined Madison's administration as Secretary of State. During the later stages of the War of 1812, Monroe simultaneously served as Madison's Secretary of State and Secretary of War. Monroe's mother died in 1772, and his father two years later. Though he inherited property from both of his parents, the 16-year-old Monroe was forced to withdraw from school to support his younger brothers. His childless maternal uncle, Joseph Jones, became a surrogate father to Monroe and his siblings. A member of the Virginia House of Burgesses, Jones took Monroe to the capital of Williamsburg, Virginia, and enrolled him in the College of William and Mary. Jones also introduced Monroe to important Virginians such as Thomas Jefferson, Patrick Henry, and George Washington.
