The Little 10 is the oldest continually running high school basketball conference in Illinois and was organized during the 1919-1920 school year with Earlville, Hinckley, Leland, Paw Paw, Plano, Rollo, Sandwich, Shabbona, Somonauk and Waterman as its charter schools. A conference tournament has been an annual event every season.
Sheridan was added in 1930, but dropped in 1939 with Serena taking their place. Rollo closed in 1954. Hinckley consolidated with Big Rock in 1957 to form Hinckley-Big Rock. In 1967, Sandwich and Plano left and Newark and Malta joined. Shabbona and Waterman consolidated to form Indian Creek in 1993, thus shortening the conference to nine teams. LaMoille joined in 1996. Malta closed in 2000. Kirkland Hiawatha joined in 2006 and that same year Earlville and Leland combined athletic programs to form Leland-Earlville.
