Similarly to his father, Harrison IV won election to five terms as Chicago's mayor. Like his father, Harrison did not believe in trying to legislate morality. As mayor, Harrison believed that Chicagoans' two major desires were to make money and to spend it. During his administrations, Chicago's vice districts blossomed, and special maps were printed to enable tourists to find their way from
brothel to brothel. The name of one Chicago saloon-keeper of the time entered the English language as a term for a strong or laced drink intended to render unconsciousness:
Mickey Finn. In the late-1890s, Altgeld aligned himself with the
free silver and
William Jennings Bryan-aligned wings of the national Democratic party. Harrison was speculated as a potential candidate for his party's
1900 presidential nomination. Despite prolonged and damaging international press coverage blaming his lax municipal enforcement for the 602 lives lost in the
Iroquois Theatre fire on December 30, 1903 (still the deadliest single-building fire in U.S. history), Harrison hoped to become the
1904 Democratic nominee for
President of the United States. However, he was unsuccessful in this effort. The nomination went to
Alton B. Parker, who was soundly
defeated by
Theodore Roosevelt. Harrison declined to seek a fifth consecutive mayoral term
in 1905, and was succeeded by fellow Democrat
Edward Fitzsimmons Dunne on April 10, 1905.
Between mayoralties In 1907, attempting to stage a return to office, Harrison unsuccessfully challenged Dunne for the Democratic mayoral nomination.
Second mayoralty In 1911, Harrison was elected to a four-year term as mayor. He as sworn in for his fifth nonconsecutive term as mayor on April 17, 1911. In 1914, Harrison convinced the city council to establish a Commission for the Encouragement of Local Art to purchase works of art by Chicago artists. Harrison personally purchased artwork from painters such as
Victor Higgins and
Walter Ufer. Harrison sought a sixth overall term as mayor
in 1915, but was defeated in the Democratic primary by
Robert Sweitzer, who went on to lose the general election to Republican
William Hale Thompson. Harrison was succeeded in office by Thompson on April 26, 1915. In 1915, when Harrison left office, Chicago had essentially reached its modern size in land area, and had a population of 2,400,000; the city was moving inexorably into its status as a major modern metropolis. He and his father had collectively been mayors of the city for 21 of the previous 36 years. A 1994 survey of experts on Chicago politics saw Harrison ranked as one of the ten-best mayors in the city's history (up to that time). ==Post-mayoralty==
