Martin Van Buren, American lawyer and politician, eighth President of the United States (born 1782)

Martin Van Buren was the eighth president of the United States, serving from 1837 to 1841. A primary founder of the Democratic Party, he served as New York's attorney general and U.S. senator, then briefly as the ninth governor of New York before joining Andrew Jackson's administration as the tenth United States secretary of state, minister to the United Kingdom, and ultimately the eighth vice president from 1833 to 1837, after being elected on Jackson's ticket in 1832. Van Buren won the presidency in 1836 against divided Whig opponents. He lost re-election in 1840, and failed to win the Democratic nomination in 1844. Later in his life, he re-emerged as an elder statesman and an anti-slavery leader who led the Free Soil Party ticket in the 1848 presidential election.
