Breese graduated from Union College in Schenectady, New York. He moved to Kaskaskia, Illinois, where he studied law in the office of Elias Kent Kane. Breese was admitted to the bar in 1820, and the following year, he served as postmaster of Kaskaskia. In 1822, Governor Shadrach Bond appointed him as state's attorney. In 1827, President John Quincy Adams appointed Breese as the U. S. district attorney for Illinois, a position he filled until President Andrew Jackson removed him. However, Breese identified himself as a Jacksonian Democrat. Breese compiled the first volume of the Illinois Reports in 1831. With the outbreak of the Black Hawk War, Breese enlisted as a private and eventually served as a lieutenant colonel of volunteers. After the war, Breese continued the practice of law, and in 1835, he was elected judge of Illinois' Second Judicial Circuit. In February of 1841, the Illinois General Assembly appointed Breese to the Illinois Supreme Court when it expanded the size of the court from four to nine members. Breese resigned from the bench after his election to the U. S. Senate in December 1842. In his term as a U.S. Senator, he supported federal land grants to the Illinois Central Railroad. Elected to the state legislature in 1850, Breese became Speaker of the State House of Representatives the following year. In 1857, he was again elected to the Illinois Supreme Court, and was reelected in 1861. He served on the state's highest court until his death.
