1933

In 1933 the Third Reich started passing laws limiting the freedoms of Jews.  In fact, between 1933 and 1945, over 2000 such pieces of legislation had been created from the national down to the municipal levels.

As early as July 9, 1933, all non-Aryans, i.e. Jews, were expelled from the Greater German Chess Federation (formed from the German Chess Federation in 1931 and reverted back to the original name in 1950).

Tarrasch wrote in his Schachzeitung as early as May 1933, "In comparison, Jewish members were always strongly represented in the chess clubs, and great international masters also emerged, who made the fame of German chess art known in the world."  (Harald E. Balló)
