Political ideologies have origins in the industrial revolution and enlightenment era belief that people could improve their lives through positive action. They provide goals for how society should be arranged and methods to achieve that ideal arrangement. The spectrum of political attitudes ranges from radical to liberal to moderate to conservative to reactionary. In Mongolia, the main political parties each claim affiliation with an ideology like liberalism for the Democratic Party or socialism for the Mongolian People's Party, but ideologies are not well defined and political attitudes are often shaped more by nationalism than ideological principles.
