During the early part of the
Original Six era, the Blackhawks considered St. Louis a secondary market and occasionally played regular season games at
St. Louis Arena, but by the time the NHL began to seriously consider expansion the Blackhawks owners insisted that St. Louis be awarded a franchise. They wanted to unload the St. Louis Arena, which they still owned but had not been well-maintained, and no longer needed St. Louis as a secondary market. So intense was their influence that the NHL formally awarded St. Louis a franchise without even receiving a formal bid from any prospective ownership group. The Blues were admitted to the NHL via the
1967 NHL expansion. The long-standing bitter rivalry between sports fans from
Chicago and
St. Louis, which are separated by 300 miles, as seen in the
Cardinals–Cubs rivalry in
Major League Baseball (MLB), has led to the Blackhawks and Blues to have an intense hatred for each other. Other than the
2020–21 season in which St. Louis played in the temporarily realigned
West Division, the two teams have been in the same division since 1970 (West in 1970–1974,
Smythe in 1974–1981,
Norris in 1981–1993, and
Central since 1993). They also qualified for the playoffs together every season from 1980 to 1997. Every Norris Division final from 1982 to 1993 involved either the Blackhawks or Blues, or both teams, except for 1987, when the
Detroit Red Wings faced the
Toronto Maple Leafs. The rivalry caught fire in the late 1980s and early 1990s, when both teams had well-known stars such as
Jeremy Roenick,
Chris Chelios, and
Ed Belfour for the Hawks and
Brett Hull,
Adam Oates, and
Vincent Riendeau for the Blues; additionally, both played in old arenas (
St. Louis Arena and
Chicago Stadium) that were regarded as two of the loudest in the league. By coincidence, both were built in 1929 and both closed in 1994 to make way for new buildings. The Blackhawks moved across the street to the
United Center, while the Blues moved into the
Kiel Center. All six
Sutter brothers would either play for the Blackhawks or Blues. In fact, left wingers
Darryl and
Brian spent their entire careers with Chicago and St. Louis respectively. They also became head coaches for the teams that they played. Brian also coached the Blackhawks for a short time. He won the
Jack Adams Award with the Blues in
1991 and was the runner-up in
2002 with the Blackhawks.
Duane and
Brent would also play and end their careers with the Blackhawks although they never played together with Chicago. Twins
Ron and
Rich would play together at one point with the Blues when Ron got traded in 1992. Also, Rich is the only Sutter brother to play for the Blackhawks and Blues. This often created a brother versus brother match-up not only in the playoffs, but as well in the season division battles that both teams got involved in. ==Notable moments==
