What was a major argument used by the Anti-Imperialist League?

The Anti-Imperialist League was founded in the late 19th century in response to the United States' expansionist policies, particularly following the Spanish-American War and the annexation of territories such as the Philippines. A significant argument presented by the League was that imperialism was fundamentally at odds with the core American values of democracy and self-governance. They contended that the United States, which had been established on the principles of liberty and freedom, should not impose its rule over other nations, often through military force.

The League's members believed that engaging in imperialism contradicted the ideals of consent of the governed, as many of the populations in the newly acquired territories had not given their approval to be ruled by an external power. This perspective emphasized that forcing control over other countries undermined the principles laid out in documents like the Declaration of Independence. Therefore, the argument that imperialism is against American values highlights the League's belief in maintaining the ethical integrity of the nation and aligning its actions with its founding ideals.

This argument resonates strongly in discussions about American identity and the implications of its overseas actions during that era.
