Who outlawed mah jong?

Mahjong was outlawed in various places during the 20th century, most notably in China. The Chinese Communist Party banned the game in 1949, viewing it as a symbol of gambling and frivolity that contradicted their ideals of a socialist society. In other regions, such as the United States, mahjong faced restrictions at different times but was not outright banned. The game's status has varied widely based on cultural perceptions and government regulations.
