Duke Maximillian of Hohenberg and Prince Ernst of Hohenberg are arrested in Austria. Both are sons of the late Archduke Francis Ferdinand, whose assassination sparked World War I, and both are active in the monarchist movement in Austria. Hermann Goering will make clear in a March 26 speech what the Nazi plans for monarchists is when he says that the monarchist movement will be treated as "high treason."
As a consequence, they are both transported to the Dachau concentration camp outside of Munich and they remain there for most of the Nazi era. Other monarchists arrested by the Nazis include Egon Fuerstenberg, a close friend of former Kaiser Wilhelm of Germany.
