The 3rd unofficial Chess Olympiad was held by German Chess Federation (Grossdeutscher Schachbund) as a counterpart of the 1936 Summer Olympics in Berlin with reference to 1924 and 1928 events.
Significantly, the "Jewish" teams of Hungary (i.e. Lajos Steiner, Endre Steiner, László Szabó, Ernő Gereben, Kornél Havasi) and Poland (i.e. Paulino Frydman, Miguel Najdorf, Henryk Friedman, Leon Kremer, Henryk Pogorieły) beat "Aryan" Germany.
Also Jewish masters from other countries played leading roles there (i.e. Movsas Feigins, Gunnar Friedemann, Imre König, Lodewijk Prins, Isakas Vistaneckis, Emil Zinner, etc.).
In that extra-Olympiad (non-FIDE) 208 participants, representing 21 countries, played 1680 games.
The Munich unofficial Olympiad was the biggest team competition ever held.
