William Jennings Bryan, a prominent American politician in the 1890s, made a speech during his political career that warned against the harms and hubris of American imperialism.  This speech was made in the context of the Spanish–American War in Cuba and in the Philippines and the aftermath.  Bryan delivered his famous speech in Indianapolis, Indiana on August 8, 1900; it was entitled "Imperialism: Flag of an Empire."  This was the speech that is most commented on and the only speech whose main subject was imperialism from Bryan that has been transcribed.  Bryan calls for a rejection of imperialism in American policy on the grounds that imperialism is directly opposed to basic American values.  He makes several references throughout the speech calling upon the ideals of democracy and basic human rights.
