After the handover of Taiwan to the Republic of China in 1945, there was brief cultural exchange with mainland China followed by further oppression. The Chinese Civil War resulted in another political separation when the Kuomintang (Chinese Nationalist Party) government retreated to Taiwan following their defeat by the communists in 1949. The influx of two million soldiers and civilians caused the population of Taiwan to increase from 6 million to 8 million. The government subsequently promoted Mandarin and banned the public use of Taiwanese as part of a deliberate political repression, especially in schools and broadcast media. In 1964 use of Taiwanese in schools or official settings was forbidden, and transgression in schools punished with beatings, fines and humiliation.
