Man with a poster or placard hanging on a string around his neck, with the slogan 'Germans! Defend yourselves! Don't buy from Jews!' (German: Deutsche! Wehrt Euch! Kauft nict bei Juden!) during the Nazi campaign to boycott Jewish shops and businesses in Berlin and Nazi Germany in April 1933. The man has a lapel pin with the swastika-and-eagle emblem of the Nazi party (NSDAP) and is standing outside a store run or owned by a Jewish businessman. The same warning sign, with text set in Fraktur typeface, is pasted on the shop window.

• The Nazi boycott of Jewish businesses (German: Judenboykott) in Germany began on April 1, 1933, and was claimed to be a defensive reaction to the international anti-Nazi boycott, which had been initiated in March 1933. It was largely unsuccessful, as the German population continued to use Jewish businesses, but revealed the intent of the Nazis to undermine the viability of Jews in Germany. It was an early governmental action against the Jews of Germany by the new National Socialist government, which culminated in the "Final Solution". It was a state-managed campaign of ever-increasing harassment, arrests, systematic pillaging, forced transfer of ownership to Nazi Party activists (managed by the Chamber of Commerce), and ultimately murder of Jewish business owners. In Berlin alone, there were 50,000 Jewish-owned businesses.

Already on March 28, the National Socialist Kampfbund for the Commercial Middle Class (Nationalsozialistischer Kampfbund für den gewerblichen Mittelstand), under Adrian von Renteln, had advanced and occupied or sealed off Jewish shops in Kiel, the Ruhr area, and in some cities in Brandenburg. On April 1, 1933, a Saturday, at 10 o'clock - in some places already the evening before - the actual boycott began. Uniformed, sometimes armed SA (Sturmabteilung), HJ (Hitler Youth), and Stahlhelm guards stood outside Jewish shops, medical practices, and law offices all over German cities, preventing potential customers from entering all day long. Signs and posters demanded: 'Germans! Defend yourselves! Don't buy from Jews! - The Jews are our misfortune! - Avoid Jewish doctors! - Don't go to Jewish lawyers!' (Deutsche! Wehrt euch! Kauft nicht bei(m) Juden! – Die Juden sind unser Unglück! – Meidet jüdische Ärzte! – Geht nicht zu jüdischen Rechtsanwälten!) Other uniformed members of the same groups spread these slogans with chants and loudspeaker vans in the streets.
