Collaborationism refers to the practice of cooperating with an occupying force or government, often during times of war or conflict. This cooperation can involve various forms of support, including political, economic, or military assistance. Individuals or groups that engage in collaborationism may do so for various reasons, such as survival, personal gain, or ideological alignment. Historically, collaborationism has been a controversial topic, as it raises ethical questions about loyalty and betrayal. Notable examples include the actions of certain groups during World War II, where some collaborated with the Nazi regime in occupied territories, leading to significant moral and social repercussions after the conflict ended.
