Senator Daniel Webster (1782-1852) was a leading American statesman during the nation's Antebellum Period. He first rose to regional prominence through his defense of New England shipping interests. His increasingly nationalistic views and the effectiveness with which he articulated them led Webster to become one of the most famous orators and influential Whig leaders of the Second Party System. Daniel Webster was an attorney, and served as legal counsel in several cases that established important constitutional precedents that bolstered the authority of the Federal government.
