The Libertarian movement is a political philosophy that emphasizes individual freedom, personal responsibility, and limited government intervention in both personal and economic matters. It advocates for civil liberties, free markets, and minimal state involvement, believing that individuals should have the right to make their own choices as long as they do not infringe on the rights of others. Founded in the 1970s, the movement has grown to include various organizations, such as the Libertarian Party, which seeks to influence policy and promote libertarian principles. Key figures in the movement include Ron Paul and Gary Johnson, who have both run for political office advocating for reduced government size and increased personal freedoms.
