As a senator from Indiana, he was a vocal supporter of the annexation of territories such as the Philippines following the Spanish-American War, arguing that it was America's duty to spread democracy and civilization. His Famous Speeches, including the "March of the Flag," reflected the prevailing attitudes of the time, promoting the belief that the United States had a moral obligation to expand its influence globally.
