North Korea functions as a highly centralized, one-party state. According to its 2016 constitution, it is a self-described revolutionary and socialist state "guided in its activities by the Juche idea and the Songun idea". In addition to the constitution, North Korea is governed by the Ten Principles for the Establishment of a Monolithic Ideological System (also known as the "Ten Principles of the One-Ideology System") which establishes standards for governance and a guide for the behaviors of North Koreans. The Workers' Party of Korea (WPK), led by a member of the Kim dynasty, has an estimated 3,000,000 members and dominates every aspect of North Korean politics. It has two satellite organizations, the Korean Social Democratic Party and the Chondoist Chongu Party which participate in the WPK-led Democratic Front for the Reunification of the Fatherland of which all political officers are required to be members.
