The Illinois–Indiana–Iowa League was a Minor League Baseball organization that operated for the better part of 60 seasons, with teams based in Illinois, Indiana, Iowa, Kansas, Minnesota, Missouri, Nebraska and Wisconsin. The league began play in 1901 and disbanded after the 1961 season. It was popularly known as the Three–I League and sometimes as the Three–Eye League. The Illinois–Indiana–Iowa League played from 1901 to 1961 with some interruptions due to world events: the league did not play in 1918 due to World War I and it had a break in 1933 and 1934 because of the Great Depression. After resuming play in 1935, it closed down in 1936, but reformed and had a six-year run from 1937 through 1942, before a break due to World War II. The league resumed play in 1946, lasting through 1961, where it was largely supplanted by the Midwest League. A Class B level league from 1902 throughout its lifespan, no other league survived for as long at that level. History The Illinois–Indiana–Iowa League was founded in 1901 with Rock Island, Illinois native Michael H. Sexton serving as the first president. Eight charter members began play in 1901. The Bloomington Blues, Cedar Rapids Rabbitts, Davenport River Rats, Decatur Commodores, Evansville River Rats, Rock Island Islanders, Rockford Red Sox and Terre Haute Hottentots were the charter teams. Bloomington, Illinois, Decatur, Illinois and Terre Haute, Indiana had left the Central League to join expansion teams in Cedar Rapids, Iowa, Davenport, Iowa, Evansville, Indiana, Rockford, Illinois, and Rock Island, Illinois and form the Class D level league. Two expansion teams, Davenport and Evansville, chose "River Rats" as their team name. For the second season, 1902, the league became Class B level league, a classification it retained for the next 59 seasons of league operation. The Illinois–Indiana–Iowa League was inactive during some years of World War I (1918), the Great Depression (1933–1934, 1936) and World War II (1943–1945), similar to many minor leagues that were forced to suspend operations or disband during those severe times. As with many minor leagues, especially at the lower classifications, league membership fluctuated a great deal over its six decades. Overall, the league hosted teams in 31 cities during its existence. At various times it had teams in such medium-sized cities as Cedar Rapids, Davenport, Bloomington, Decatur, Danville, Peoria, Springfield, Evansville and Terre Haute. It was a Class B league in the old classification
