The beginning of the end was when Arkansas announced it would leave for the Southeastern Conference in 1990. The death blow came in 1993 when Texas, Texas A&M, Texas Tech, and Baylor accepted invitations to join with the members of the Big Eight Conference to form the Big 12 Conference. Soon afterward, SMU, TCU and Rice accepted invitations to join the Western Athletic Conference, while Houston joined Conference USA. In May 1996, after the completions of championship matches in baseball and track & field, the Southwest Conference was officially dissolved.
