Records show that football was played at Southwestern University as early as 1895, but the school's first officially recognized team was not formed until 1908. They were charter members of the Texas Intercollegiate Athletic Association along with Austin College and Trinity in 1908, and of the Southwest Conference in 1914. They then left the Southwest Conference prior to the 1918, but continued to compete within the TIAA until 1925, when the departure of Rice caused the TIAA to split. At that point, Southwestern helped form the Texas Conference along with Austin College, Howard Payne University, Simmons University, and Trinity University. Southwestern would remain in the Texas Conference until its football program was disbanded on April 27, 1951. Prior to the 1940s, Southwestern was considered a "small time" football program, and only received national media attention about once yearly, whenever it faced a major college team. During the Second World War, however, Southwestern became a formidable football power because of its sponsorship of a V-12 Navy College Training Program, which was gained through the actions of then Texas Congressman Lyndon B. Johnson. The Navy program gave it a pool of experienced and skilled players, which was a competitive advantage over other teams that fielded men too young or physically unfit for military service. In 1943, Southwestern's team boasted seven former starters from Texas and varsity players formerly with Baylor. Despite the influx of stars, Southwestern still had to contend with players leaving midseason to report for military training. During the 1943 season, Southwestern climbed as high as the eleventh-ranked team in the nation in the Associated Press Poll. Southwestern lost only one game during the season, and won the Sun Bowl against New Mexico, 7–0. After the 1944 season, the Sun Bowl invited Southwestern to return to face the National University of Mexico. Southwestern routed the Pumas, 35–0, to set a scoring record for the game before 13,000 spectators. After the conclusion of the Second World War, and the concurrent disbandment of the military training programs on campus, Southwestern's football performance declined. Southwestern University disbanded its football team in April 1951 due to budget constraints.
Reinstatement
On October 28, 2011, The Southwestern University board of trustees voted to reinstate the university's football program. The reinstatement was made possible by $6 million in gifts. $5 million was pledged by Joe Seeber, a 1963 Southwestern graduate. However, Seeber later withdrew his pledge. The other $1 million was donated by Red McCombs, who attended Southwestern and played football. “As the oldest university in Texas, we realize the importance many people place on football,” said university president Jake B. Schrum. “There are many bright young men who want to play football in college who find NCAADivision III appealing. It is important for us to be back in the game." On February 27, 2012 Joe Austin was hired as the new head football coach at Southwestern. Austin came to Southwestern from Hanover College where he was the head coach for the 2008 through 2011 seasons. During that time Austin rebuilt a program that had suffered four consecutive losing seasons prior to his arrival. In just Austin's third season Hanover posted a 7–3 record while finishing second in the league. Austin's team finished second again in his fourth and final season of 2011. While at Hanover, Austin produced three NCAA statistical champions: Tyler Thiems 2008, Correy Stewart 2009, and Daniel Passafiume 2009. The Pirates resumed play on September 7, 2013 with the first game a 44–14 loss to Texas Lutheran at the new Georgetown stadium complex, just up the road from the campus. In just their fourth season of play the Pirates posted a 6–0 record in claiming the Southern Collegiate Athletic Conference championship. In 2017, the Pirates began play in the American Southwest Conference.
