The Regina Rugby Club changed their colours again in 1912 to red and black and began an era of western football dominance. For every season of play in the SRFU, Regina won the league championship, exerting their prowess over teams from Moose Jaw, Saskatoon, and any other clubs in Saskatchewan. Beginning in the 1912 season, Regina won seven straight WCRFU titles, excluding 1917 and 1918 when World War I interrupted league play. In 1921, the western champion was invited to compete for the Grey Cup national championship for the first time, but it was also the first time since 1911 that the Regina Rugby Club didn't win the West Championship as the Edmonton Eskimos traveled east to play in the 9th Grey Cup.
