The organization in question was established in the United States in 1898 to oppose the nation’s policy of colonial expansion, particularly following the Spanish-American War. Its members believed that imperialism violated the fundamental principles of republicanism and self-governance upon which the country was founded. A diverse coalition of individuals, including prominent intellectuals, politicians, and activists, comprised its membership. These individuals shared the conviction that acquiring and governing overseas territories was morally wrong and detrimental to American interests.
The significance of this movement lies in its articulation of a principled opposition to expansionism during a period of intense nationalistic fervor. It served as a critical voice, raising concerns about the potential negative consequences of colonialism, such as the exploitation of indigenous populations, the undermining of democratic values at home, and the entanglement of the U.S. in foreign conflicts. Furthermore, its actions helped shape public debate on the role of the United States in the world and influenced subsequent anti-colonial movements globally.
