Early political career[edit]
Painting of Van Buren by Daniel Dickinson, c. 1820s
Upon returning to Kinderhook in 1803, Van Buren formed a law partnership with his half-brother, James Van Alen, and became financially secure enough to increase his focus on politics.[32] Van Buren had been active in politics from age 18, if not before. In 1801, he attended a Democratic-Republican Party convention in Troy, New York, where he worked successfully to secure for John Peter Van Ness the party nomination in a special election for the 6th Congressional District seat.[33] Upon returning to Kinderhook, Van Buren broke with the Burr faction, becoming an ally of both DeWitt Clinton and Daniel D. Tompkins. After the faction led by Clinton and Tompkins dominated the 1807 elections, Van Buren was appointed Surrogate of Columbia County, New York.[34] Seeking a better base for his political and legal career, Van Buren and his family moved to the town of Hudson, the seat of Columbia County, in 1808.[35] Van Buren's legal practice continued to flourish, and he traveled all over the state to represent various clients.
