German ice hockey changed significantly with the formation of the
Deutsche Eishockey Liga (DEL) in 1994. Its growing influence also brought growing independence from the
German Ice Hockey Federation (DEB) which had regulated ice hockey in Germany for many decades.
Pre-DEL era The first incarnation of the Adler Mannheim was the 'Mannheim Ice and Roller Sport Club'
(Mannheimer Eis- und Rollsport-Club or
MERC), founded on 19 May 1938. On 19 February 1939, they had their introductory match in the brand new Friedrichspark Stadium. The match against the winner of the German Championship was lost 0–11, but the following seasons were more and more successful. However, due to the ongoing Second World War, it was difficult to play a regular season without some limitations. In 1942, after the Mannheim was qualified for the finals, the proclamation of the
total war led to the cancellation of the finals, less than 24 hours before their scheduled beginning. On 5 June 1943, the
Eisstadion am Friedrichspark was destroyed by an air attack on Mannheim. After the end of the Second World War in 1945, it took another four years before the hockey club began playing once again. In the 1951/52 season, Mannheim again had a team to play in a regular team, but it was not very successful. The most successful game in this time was a 10–2 victory against a team of American soldiers based in the Mannheim-area.
Promotion to first division and first German championship In 1978, the MERC achieved promotion to the first division of
Eishockey Bundesliga. In order to be able to set up a team with the limited budget, the MERC and coach
Heinz Weisenbach had to get innovative. Weisenbach traveled to North America to search specifically for players with German roots. With
Harold Kreis,
Manfred "Mannix" Wolf,
Roy Roedger and
Peter Ascherl, the first "German-Canadians" were transferred into the Eishockey Bundesliga. Additionally, Mannheim acquired the national goalkeeper
Erich Weishaupt from the Berliner Schlittschuhclub (Berliner SC). After a sixth place in their debut season, Mannheim strengthened their squad with
Ron Andruff and
Holger Meitinger and the national players Mannheimer
Marcus Kuhl (Cologne) and
Peter Obresa (Bad Nauheim). In a complicated tournament mode, from preliminary round, second round and championship round, the MERC would finally win the German championship for the first time. The title win was solidified with a victory in Berlin, and the Mannheim players warmed-up in
tailcoats and
top hats before their final, inconsequential home game against Cologne EC.
DEL era Four DEL championships in 5 years In 1994, the Mannheimer ERC was a founding member of the
Deutsche Eishockey Liga (DEL). While the organization of the MERC continues to exist to the present day, the professional hockey team changed its name to
Adler Mannheim and was transformed into an independent legal entity called "Die Adler Mannheim Eishockey Spielbetriebs GmbH + Co. KG". The old organization MERC still performs in the amateur and junior sectors, including the successful junior team
Jungadler Mannheim ('Mannheim Young Eagles') (
DNL). The first two seasons in the DEL ended in playoff quarter finals, but the following season marked the first full success of the DEL era: the Adler Mannheim swept through the playoffs. With the minimum number of nine games, they won the championship in 1997. After also winning the championships in 1998 and 1999, head coach
Lance Nethery and several players left the team. After a disastrous start to the regular 1999–2000 season, the Adler reached the playoffs again, but were beaten in the quarter-finals again. After that season, head coach
Chris Valentine was released and was succeeded by
Bill Stewart. In 2000–01, the Adler returned to winning ways with the fourth DEL championship in five years. In their final season at Friedrichspark, Mannheim native
Jochen Hecht (
Buffalo Sabres),
Cristobal Huet (
Montreal Canadiens),
Yannick Tremblay (
Atlanta Thrashers) and
Sven Butenschön (
New York Islanders) joined the Adler during the
2004–05 NHL lockout. The team made it to the finals, but were defeated by the
Eisbären Berlin.
Move to SAP Arena and 5th DEL championship The following season was disastrous. In their new home, the
SAP Arena, the team was placed tenth at the end of the regular season. It was the first time in 26 years that the Adler Mannheim had not qualified for the playoffs. Making several changes ito the team roster, the team celebrated its resurrection in the following
2006–07 season. After winning the
German Cup, they finished in first place in the regular season and then won their fifth DEL Championship.
Adler Mannheim and the NHL On 6 July 2010, the Adler Mannheim competed against the San Jose Sharks in the 2011
NHL Premiere Challenge 2010. German national player
Manuel Klinge scored for Mannheim in the 5th minute, San Jose equalized with a goal by
Jamie McGinn (54th minute). After
Devin Setoguchi scored for San Jose, Mannheim's
Jame Pollock scored the equalizer at minute 57. In the shoot-out, it was
Dan Boyle who scored with the decisive penalty shot for the Sharks. In July 2011, Mannheim entered a developmental partnership with the
Toronto Maple Leafs of the
NHL. The Adler participated in the
2011 NHL Premiere series, losing to the
Buffalo Sabres 8–3. The Sabres (who counted among its players Mannheim native
Jochen Hecht) were very well received in Mannheim, and later that season, a contingent of Adler fans traveled to Buffalo and Toronto to witness games hosted by the Sabres and Maple Leafs. During the
2012 NHL lockout, the Adler Mannheim became a popular team for the lockout players again. The former Mannheim players
Dennis Seidenberg (
Boston Bruins) and
Marcel Goc (
Florida Panthers) joined the team once more. They were followed by
Jason Pominville, captain of the
Buffalo Sabres and again
Jochen Hecht, who was a free agent since his injury in early 2012. Hecht signed a contract (with an NHL-Out paragraph) until 2014, but after the lockout came to an end, he was offered a new one-year contract by the Buffalo Sabres. After the Sabres' contract expired, Hecht announced his intention to return to Mannheim to finish his professional career.
6th DEL championship and turbulent times On 19 June 2014, Mannheim hired Boston Bruins assistant coach
Geoff Ward as their new head coach. After winning the regular season with nine points ahead of the second-placed EHC Red Bull München, the Adler won the quarter-final series against the Nürnberg Ice Tigers 4–1. In the semi-finals, the Adler swept Grizzly Adams Wolfsburg with 4–0 victories – even after being down 0–3 goals in three of the games. In the final, Mannheim finally met ERC Ingolstadt. After a devastating 1–6 loss in the third game with Ingolstadt taking the 2–1 lead in the final series, the Adler turned the series and won all subsequent games. With 4–2 victories, the Adler Mannheim were able to win their sixth DEL championship. After the 2014–15 season, Ward returned to the
NHL and was replaced by
Greg Ireland. Ireland was sacked in February 2016, and
Craig Woodcroft, who had joined the Adler coaching staff in 2014, was promoted to head coach. Woodcroft failed to guide the Adler squad to the playoffs and left after the 2015–16 season. In May 2016,
Sean Simpson was named new head coach.
Successful transition and 7th DEL championship On 4 December 2017, GM
Teal Fowler, head coach Simpson and assistant coach
Colin Muller were sacked due to unsatisfactory results. Bill Stewart, who had guided the club to the 2001 DEL title, took over the head coaching job. During the 2017–2018 season, the Adler Mannheim announced
Jan-Axel Alavaara as the new GM and
Pavel Gross as their new head coach assisted by
Mike Pellegrims and
Pertti Hasanen. The Adler finished their regular season 2018–19 at the top of the standings table with a new point average record of 2,23 points per game and won the DEL title 2018–19 defeating
EHC Red Bull München 4–1 in the playoff finals. During the summer break, the Adler Mannheim released their long-time team captain Marcus Kink – his successor being NHL veteran and German national player
Marcel Goc. Also during the summer break of 2019, Adler Mannheim's rookie defenseman
Moritz Seider was drafted in the first round of the NHL Entry Draft, sixth overall, by the Detroit Red Wings. Seider was the first German defenseman to be selected in the first round of an NHL Entry Draft, and the fourth-highest German-born player to be selected until
Tim Stützle was selected third overall by the
Ottawa Senators in the
2020 NHL Draft. On 14 July 2019, Seider was signed to a three-year, entry-level contract with the Detroit Red Wings. On 27 December 2020, Stützle signed a three-year, entry-level contract with the Ottawa Senators. After a poor start to the 2023/24 season, general manager
Jan-Axel Alavaara and head coach Johan Lundskog were dismissed mid-season and American former
NHL head coach
Dallas Eakins was announced as new head coach and general manager on 27 November 2023. ==Honours==
