The American Anti-Imperialist League was an organization established on June 15, 1898, to battle the American annexation of the Philippines as an insular area. The anti-imperialists opposed forced expansion, believing that imperialism violated the fundamental principle that just republican government must derive from "consent of the governed." The League argued that such activity would necessitate the abandonment of American ideals of self-government and non-intervention—ideals expressed in the United States Declaration of Independence, George Washington's Farewell Address and Abraham Lincoln's Gettysburg Address. The Anti-Imperialist League was ultimately defeated in the battle of public opinion by a new wave of politicians who successfully advocated the virtues of American territorial expansion in the aftermath of the Spanish–American War and in the first years of the 20th century, although the organization lasted until 1920.

Faneuil Hall is a marketplace and meeting hall located near the waterfront and today's Government Center, in Boston, Massachusetts. Opened in 1742, it was the site of several speeches by Samuel Adams, James Otis, and others encouraging independence from Great Britain. It is now part of Boston National Historical Park and a well-known stop on the Freedom Trail. It is sometimes referred to as "the Cradle of Liberty," though the building and location have ties to slavery.
