History
European Indoor Championships is the oldest major indoor championships in the world. Officially inaugurated in 1970, but previously had held four times under the name of European Indoor Games (1966-69). The championships held annually until 1990, the year it was changed to current biennial format. Another time-slot change occurred after the 2002 edition to synchronize the event with World Indoors.
The event traditionally led by Soviets, Germans, and (sometimes) Polish teams, but several editions topped by nations such as Czechoslovakia (1984), Great Britain (2007), or France (2011).
If we consider Germany as combined with East Germany, the country has more medals than any other country by far. But taking apart as correction of political representation, Soviet Union still on top of medal table despite dissolved some 30 years ago.
