Pitești Prison was a penal facility in Pitești, Romania, best remembered for the reeducation experiment which was carried out between December 1949 and September 1951, during Communist party rule. The experiment, which was implemented by a group of prisoners under the guidance of the prison administration, was designed as an attempt to violently "reeducate" the mostly young political prisoners, who were primarily supporters of the fascist Iron Guard, as well as Zionist members of the Romanian Jewish community. The Romanian People's Republic adhered to a doctrine of state atheism and the inmates who were held at Pitești Prison included religious believers, such as Christian seminarians. According to writer Romulus Rusan, the experiment's goal was to re-educate prisoners to discard past religious convictions and ideology, and, eventually, to alter their personalities to the point of absolute obedience. Estimates for the total number of people who passed through the experiment range from at least 780 to up to 1,000, to 2,000, to 5,000. Journalists Laurențiu Dologa and Laurențiu Ionescu estimate almost 200 inmates died at Pitești, while historian Mircea Stănescu accounts for 22 deaths during the period, 16 of them with documented participation in the "re-education".
