Imperialist tendencies refer to the attitudes and practices that promote the expansion of a nation's influence or control over other territories and peoples. This concept is closely connected to notions of superiority and dominance, often justified by social, economic, or cultural motivations. The rise of these tendencies was fueled by ideologies such as Darwinism and Social Darwinism, which provided a pseudo-scientific rationale for imperial expansion and the belief in the superiority of certain races and cultures over others.
