After the war, Kim Il-Sung University became known as a hotbed of intellectual dissent. Academics supported more intellectual freedoms than Kim loyalists, and disadvantageous factions within the Workers' Party of Korea were over-represented in university staff. Following the Revolutions of 1956 in Hungary and in Poland, North Korean exchange students were quickly repatriated from the affected countries. The students started asking "improper" questions on campus, causing alarm. After that, up to one hundred students and several prominent staff members were purged. The purging of the university gave further impetus to purges against functionalists all over the country.
