Anti-imperialism activity at Faneuil Hall on June 15, 1898, in response to the US take over of Cuba, the Philippines, and Puerto Rico, and the creation of the Anti-Imperialist Committee of Correspondence, which became the New England Anti-Imperialist League. The League helped shape national debate about US colonization and promoted the right to self-determination. It challenged the annexation of the Philippines and was in conflict with powerful political proponents of imperialism, like Henry Cabot Lodge of Boston. The local chapter was diverse and included women, African Americans, labor activists, and Catholics.
