DeWitt Clinton (1769-1828) was one of the nation's strongest political leaders in the first quarter of the nineteenth century, serving as mayor of New York City, governor of the state, and narrowly losing the Presidential race of 1812 to James Madison. Patrician in his sentiments, Clinton nevertheless invented new forms of party politics. His greatest achievement, the Erie Canal, hastened the economic expansion of the country, altered the political geography of the nation, set an example for activist government, and decisively secured New York City's position as America's first and foremost metropolis. This new book relates the full biography of one of the most important political figures in US history.
