The tournament features the top teams of the professional baseball leagues in Europe, and is the first tier of the four competitions organized by WBSC Europe, alongside the second-tier European Cup, third-tier Federation Cup, and fourth-tier Federation Cup Qualifiers, which operate with a promotion and relegation system for its federations.

[1][2] The first season of the tournament was held in 1963 and was won by the Picadero Jockey Club Barcelona.

In early 2024, WBSC Europe announced a restructuring of its European club competitions, with the top tier Baseball European Champions Cup now being played in a full-season format at each team's venues, instead of a tournament hosted in one location.

The inaugural tournament under the new format will feature only 4 teams from Germany and Czech Republic, with expansion planned for the future.

The lower-tier competitions are keeping their tournament structure, with promotion and relegation for its federations.
