The Communist Party is organized from the bottom up. Small cells exist in every unit of Soviet society—office, factory, shop, school, institute, laboratory. These form a local organization directed by a party secretary, appointed by the district or republic secretary, all controlled by the Party Secretariat in Moscow. In theory, the Party Congress, meeting every three to five years, is the supreme authority. In reality, of course, the party is run by an inner oligarchy, the 12‐ to 14‐member Politburo.
