Red Justice (Serbo-Croatian : Crvena pravda) was a faction of the Communist Party of Yugoslavia (KPJ) that was known for terrorist acts against the government of the Kingdom of Yugoslavia.
On 30 December 1920, the government issued Obznana , a decree outlawing the KPJ. Red Justice attempted to assassinate the Regent Alexander on 28 June 1921, and then killed former Interior Minister Milorad Drašković on 21 July. This led to the authorities proclaiming the Law on the Protection of the Realm, turning the KPJ ban into legislation on 2 August. It caused the annulment of the KPJ seats in the national assembly two days later, and numerous covert police agents infiltrating the KPJ. [1] [2]
