After the founding of the new country in 1949, the party had consolidated its control over Chinese society through mass campaigns like Land Reform (1947-1952), the Campaign to Suppress Counterrevolutionaries (1950-1953), the Three-Anti and Five-Anti Campaigns (1951-1952), the Campaign to Resist U.S. Aggression and Aid Korea (1950-1953), and the Sufan Movement (1955). The government also completed the Ethnic Classification in 1954 which aimed at sorting and categorizing the hundreds of distinct ethnic communities within the country, the result of which served as the basis for future policy on nationalities.
