Who was the first president born a U.S. citizen?

Martin Van Buren was the first president who was a U.S citizen at birth. He was the eighth president of the United States; he followed Andrew Jackson. He served as president from 1837 to 1841.

Before he was president, Van Buren was vice president for President Jackson. He only served one term as president, and his vice president was Richard M. Johnson. Van Buren was defeated by William Henry Harrison in 1841. Harrison died after only a month in office, as he caught pneumonia after giving an extra-long inauguration speech on a day that was too cold. He was succeeded by John Tyler, who also only served one term.
