On November 6, 1789, Pope Pius VI erected the Diocese of Baltimore, the first Catholic diocese in the United States, and the area that became Indiana fell under the authority of John Carroll, Bishop of Baltimore. In 1791 Bishop Carroll sent Father Benedict Joseph Flaget to succeed Father Gibault at the fledgling Saint Francis Xavier Parish. Father Flaget, who arrived at Vincennes in 1792, opened a school and held classes at Saint Francis Xavier before he was recalled to Baltimore in 1795. John Francis Rivet, who came to Vincennes in 1796 as Father Flaget's successor, received an annual teacher's salary of $200 from the U.S. Congress, making him the first public school teacher in the Northwest Territory.
