After studying abroad, Morris returned to Philadelphia and studied law; he was admitted to the bar and commenced practice in Canandaigua, New York. He was a member of the New York State Assembly from 1794 to 1796.[4]
Morris was elected as a Federalist to the Seventh Congress, holding office from March 4, 1801, to March 3, 1803.[5] He was not a candidate for renomination, and resumed the practice of law in New York City in 1803. He was appointed United States Marshal for the Southern District of New York in 1816, 1820, 1825, and 1829.[4]
Morris was said to have settled the peace with the Six Nations of the Iroquois Confederacy, four of whom had sided with the British during the Revolution.[6] His father then sold his substantial property in Western New York, which the younger Morris oversaw,[7] to the Holland Land Company in 1792–1793 for redevelopment in parcels,[8] although some sources identify the sale at five years later, in 1797–1798.[9]
