The Illinois-Indiana-Iowa League was a minor league baseball organization that operated for the better part of 60 years, mostly in those three states. It was popularly known as the Three-I League and also sometimes jokingly as the Three-Eye League.
The league began play in 1901 and disbanded after the 1961 season. It had also been inactive during some years of World War I, the Great Depression and World War II, following the lead of many minor leagues that suspended operations or failed during those severe times.
As with many minor leagues, especially at the lower classifications, its membership fluctuated a great deal over its six decades. 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 system that ran from Class D up to Class Triple-A. Since 1961 its territory has largely been supplanted by the Midwest League, which began as a Class D organization in 1947 and is now Class A under the restructuring of the minors that occurred in 1963.
The league's unique name made it a convenient reference point for any mention of the minor leagues. Casey Stengel made the following comment in later life, evidently still feeling stung from having been traded by the New York Giants to the Boston Braves in the 1923-1924 off-season, despite having hit 2 game-winning home runs in the World Series: "It's lucky I didn't hit 3 home runs in three games, or McGraw would have traded me to the 3-I League!"
Bloomington, Illinois, Decatur, Illinois and Terre Haute, Indiana left the Central League and joined this league. New teams in Cedar Rapids, Iowa, Davenport, Iowa, Evansville, Indiana, Rockford, Illinois, and Rock Island, Illinois formed and joined the league. Two of the teams, Davenport and Evansville, chose "River Rats" as their team name.
