The term "Dutch Underground" refers to a network of resistance movements in the Netherlands during World War II. These groups worked to oppose the German occupation, providing support to those persecuted, including the Jewish population. They engaged in various activities, such as hiding people, distributing anti-Nazi propaganda, and sabotaging German operations. One of the most notable figures associated with the Dutch Underground is Anne Frank, whose diary documented her life in hiding. The resistance also included various organizations, such as the Dutch National Socialist Movement, which played a role in the broader European resistance efforts against Nazi Germany.
