the 2003–04 season In 2005–06 and 2006–07, the Eisbären were the German representative at the Spengler Cup in Davos, Switzerland. In 2004–05, a season marked by the 2004–05 NHL lockout, saw the Eisbären capture their first DEL championship. With the help of NHL veterans such as Erik Cole, Nathan Dempsey, and Olaf Kölzig, Berlin beat Mannheim in three games. The title was defended successfully in 2006 against the DEG Metro Stars. Their third DEL championship was captured in 2008, when the Eisbären beat Kölner Haie in the final round of the play-offs. In 2008, the Eisbären hosted the NHL's Tampa Bay Lightning in a pre-season game, which the Lightning won 4:1. The fourth DEL title followed in 2009, when the DEG Metro Stars were beaten 3:1 in a best-of-five final play-off round. In 2010, the team won the European Trophy, continuing its success on an international scale. A fifth DEL title was won in 2011, when the Grizzly Adams Wolfsburg were swept in the final round of the play-offs. A sixth title was won in 2012, after a full length best-of-five final against Adler Mannheim, with a seventh coming the next year after a 3:1 series victory over Kölner Haie. With their 2013 title, the Eisbären Berlin had won 7 DEL titles, including three straight, making them the DEL championship record holder for several years; Adler Mannheim later tied the record in 2019. In the 2016–17 league season, the Eisbären Berlin drew an average home attendance of 12,052. Eisbären ultimately won their eighth DEL championship in 2021, defeating Grizzlys Wolfsburg 2:1 in a best-of-three, and in the process reclaiming the record for most DEL championships.
