South Dakota Intercollegiate Conference


The South Dakota Intercollegiate Conference was an NAIA-associated collegiate athletic conference that ceased operations following the 1999–2000 academic school year when it merged with the North Dakota College Athletic Conference to form the Dakota Athletic Conference. The SDIAC was formed in 1917 from twelve schools, though membership was down to five during World War II, as the religious schools formed the South Dakota College Conference. Those schools joined back in by 1948. From 1995 to 2000 seasons, the league was known as the South Dakota-Iowa Intercollegiate Conference, thanks to the addition of Dordt and Westmar colleges in Iowa. Westmar closed in 1997. The SDIIC dissolved in 2000, with half of the schools heading to the DAC, while the other half joined the Great Plains Athletic Conference.
