Despite his wartime activities, Burr finished his studies and was admitted to the bar at Albany, New York in 1782, the year of his marriage.
He began practicing law in New York City the following year after the British evacuated the city.

Burr served in the New York State Assembly from 1784 to 1785.
In 1784 as an assemblyman, Burr unsuccessfully sought to abolish slavery immediately following the American Revolutionary War.

Also, he continued his military service as a lieutenant colonel and commander of a regiment in the militia brigade commanded by William Malcolm.
He became seriously involved in politics in 1789, when George Clinton appointed him as New York State Attorney General.
He was also Commissioner of Revolutionary War Claims in 1791.
In 1791, he was elected by the legislature as a Senator from New York, defeating incumbent General Philip Schuyler.
He served in the Senate until 1797.

Burr ran for president in the 1796 election and received 30 electoral votes, coming in fourth behind John Adams, Thomas Jefferson, and Thomas Pinckney.
He was shocked by this defeat, but many Democratic-Republican electors voted for Jefferson and no one else, or for Jefferson and a candidate other than Burr.
Jefferson and Burr were again candidates for president and vice president during the election of 1800.
Jefferson ran with Burr in exchange for Burr working to obtain New York's electoral votes for Jefferson.

President John Adams appointed Washington as commanding general of U.S. forces in 1798, but he rejected Burr's application for a brigadier general's commission during the Quasi-War with France.
Washington wrote, "By all that I have known and heard, Colonel Burr is a brave and able officer, but the question is whether he has not equal talents at intrigue."
Burr was elected to the New York State Assembly in 1798 and served there through 1799.
During this time, he cooperated with the Holland Land Company in gaining passage of a law to permit aliens to hold and convey lands.
National parties became clearly defined during Adams' Presidency, and Burr loosely associated himself with the Democratic-Republicans.
However, he had moderate Federalist allies such as Senator Jonathan Dayton of New Jersey.
