Definition of "proletarian"

While the May 30th Movement is usually perceived by historians as essentially a Communist-instigated urban proletarian movement, in the suburban countryside in Xihua county the antiforeign struggle attracted a sizable number of peasants. Surprisingly, the Xihua boycott in Youth Village (qingnian cun) was organized in the name of a peasant organization, the Central Plain Peasant Association (Zhongyuan nongmin xiehui).
