The term "Nazi occupation" refers to the period during World War II when the Nazi regime of Germany took control of various countries in Europe. This occupation began after the Nazi invasion of Poland in 1939 and expanded to include nations such as France, Belgium, and the Netherlands. The occupation often involved military governance, suppression of local governments, and the implementation of harsh policies against resistance. During the Nazi occupation, many countries experienced severe repression, including the persecution of Jewish people and other minority groups. The occupiers imposed strict laws, forced labor, and widespread violence, leading to significant suffering and loss of life. Resistance movements emerged in many occupied countries, fighting against the oppressive regime and seeking to restore freedom.
