Ambrose helped manage Montpelier for both his father and older brother until his death in 1793. Madison succeeded Jefferson with a victory in the 1808 presidential election. After diplomatic protests and a trade embargo failed to end British attacks against American shipping, he led the United States into the War of 1812. Throughout the United States, opponents of the Constitution, known as Anti-Federalists, began a public campaign against ratification. In response, Alexander Hamilton and John Jay began publishing a series of pro-ratification newspaper articles in New York. After Jay dropped out from the project, Hamilton approached Madison, who was in New York on congressional business, to write some of the essays. Montpelier, his family's plantation, has been designated a National Historic Landmark. The James Madison Memorial Building is a building of the United States Library of Congress and serves as the official memorial to Madison. In 1986, Congress created the James Madison Memorial Fellowship Foundation as part of the bicentennial celebration of the Constitution.
