After his wartime military service came to an end, Bartholomew became involved in politics. In 1818, he served on the
Indiana General Assembly, and was elected to the
Indiana Senate in 1820. He was selected to be a member of the commission that would choose the location of the capital of Indiana, and helped pick
Indianapolis as the new site. He would often claim "to have dug the first dirt for the State capital." Though he moved home in 1822, he continued to serve the state on the board of commissioners for land deeds. He retired in 1825. In 1831 Bartholomew was the bondsman for his neighbor Dr. Andrew P. Hay, who had embezzled government funds. As a result of the embezzlement, Bartholomew sold his farm and moved to
McLean County, Illinois. He and his son planted a new town named Clarksville, north of present-day Bloomington, which was abandoned by the 1850s. He was an avid supporter in William Henry Harrison's presidential campaign in 1840. In the fall of that year, his health began declining. He died on November 3, 1840, and was buried in Clarksville cemetery in McLean County. His grave marker was placed by the
Grand Army of the Republic in 1894 with the inscription "To the memory of Maj. Genl. Joseph Bartholomew Hero of Tippecanoe. He also fought in the Revolutionary War, The War of 1812, & the
Black Hawk War." In 1973, a stone monument marking the approximate location of Gen. Bartholomew's Block House Fort (built during the Black Hawk War) was placed in the Dawson Cemetery in McLean County, IL. ==Notes==
