I posted this in another thread but deleted it as there's no need to distract from the subject of that thread.
As a long-time fan of the Valley, recent membership changes made me nostalgic for MVC alignments of years past as well as excited for the future of the league with the recent, very solid additions. I translated the MVC membership timeline from Wikipedia into a year-by-year membership change list for the conference. I initially published that in this thread but it was extremely long and difficult to read. I'd be happy to provide that year-by-year list to anyone who wants it.
In creating that list, I did not count affiliate memberships (including football-only when the league sponsored football). It's fascinating to see how our conference has responded to member departures over more than 100 years to end up with our current alignment, which appears to be one of its strongest alignments since the early days of the MVC.
My narrative of MVC membership changes is below, which summarizes the list. I recommend reading the narrative in Ken Burns' voice:
The Missouri Valley Conference was founded in 1907 when Drake, Iowa State, Kansas, Missouri, Nebraska, and Washington University in St. Louis formed what would become the second-oldest conference in NCAA Division I (only the Big Ten predates the MVC). The conference remained at six members until Kansas State and Grinnell College joined in 1913 and 1918, respectively, bringing the league to eight members.
Nebraska briefly disaffiliated from the MVC in 1919. Oklahoma’s addition the same year grew the MVC to nine members after Nebraska rejoined the conference in 1921. The MVC expanded its Oklahoma presence in 1925 when Oklahoma State became the MVC’s tenth member school.
1928 ushered in the MVC’s first, and most significant, realignment. All of the MVC’s public schools, except for Oklahoma State, exited the MVC. The mass exodus of almost all the large state schools (Iowa State, Kansas, Kansas State, Missouri, Nebraska, and Oklahoma) dropped league membership from ten members to four and threatened the very existence of the MVC. Creighton was brought in that year to bump league membership to five and stop the bleeding. Butler would join in 1932.
The MVC remained at six members even upon Butler’s departure in 1934, as Tulsa joined the same year. The MVC began expanding again, adding Washburn in 1935 and Saint Louis in 1937 to bring league membership to eight. Grinnell abandoned the MVC, and Division I membership altogether, in 1939, as would Washburn in 1943, briefly returning the MVC to six members during the Second World War.
Wichita State joined the MVC in 1945 to give Oklahoma State another state-supported conference opponent. When Washington University left two years later, the MVC became a six-member league once again, with four private and two public universities. Creighton folded its football program in 1948 as well as its MVC membership, but the public-private balance would not change as private Bradley joined upon Creighton’s departure to the ranks of the Division I independents.
The University of Detroit gave the MVC another private league member the following year, and Houston’s addition in 1951 gave the MVC its eighth member school. Drake and Bradley briefly surrendered their conference memberships in 1952 in protest of Oklahoma State's and the MVC's response to the Johnny Bright incident. Bradley would return in 1955, and Drake in 1956, the same year Oklahoma State parted ways with the MVC after 31 years in the league.
Detroit’s departure in 1957 was met with the additions of Cincinnati and North Texas as the MVC began to expand its public footprint once again. Houston would leave in 1960, but the MVC added Louisville in 1963 and Memphis in 1968 to create a nine-member, majority-public MVC composed of five public (Wichita State, Cincinnati, North Texas, Louisville, and Memphis) and four private (Tulsa, Saint Louis, Bradley, and Drake) members.
The MVC continued adding public universities, beginning with New Mexico State and West Texas A&M in 1970 to replace Cincinnati. The MVC competed as a ten-member league until Memphis (1973) and Saint Louis (1974) resigned from the conference.
The MVC’s response in 1975 to the defections of North Texas and Louisville set the tone for the most stable stretch of MVC membership in conference history, and the one most basketball fans are familiar with today. Southern Illinois joined the league that year, as did Indiana State the following year. Creighton returned to the MVC in 1976 when NCAA rule changes made it more difficult for unaffiliated teams to earn NCAAT berths. Illinois State’s addition in 1980 would give the MVC ten league members and a familiar footprint of Tulsa, Wichita State, Bradley, Drake, New Mexico State, West Texas A&M, Southern Illinois, Creighton, Indiana State, and Illinois State.
The far-western pair of New Mexico State and West Texas A&M would leave the MVC for more geographically sensible conferences in 1983 and 1986, respectively. The MVC responded by adding rising Division I newcomers in Missouri State (1990) and Northern Iowa (1991). The league threw a bone to the private members by adding Evansville (1994) two years before Tulsa departed for the football-focused Western Athletic Conference in 1996.
The MVC would remain a five public, five private, geographically compact and very stable conference from 1996 to 2013. Seventeen years of peace and stability in the Valley ended when the Big East Conference came calling for Creighton in 2013. The MVC responded with the addition of the institutionally-similar Loyola Chicago the same year. When Wichita State left in 2017 to join some former MVC foes in the American Athletic Conference, Valparaiso would keep the MVC at ten members and two flags in the Chicagoland market.
Loyola’s stint in the MVC turned out to be brief, as the school announced it would join the Atlantic 10 Conference in 2022. The MVC responded with its largest single-year addition in the 115-year history of the league by announcing the additions of public Murray State and Illinois-Chicago and private Belmont, reshaping the league into its largest yet (twelve members).
