Until 1944, the group active inside Romania became split between the ""prison faction"" (political prisoners who looked to Gheorghiu-Dej as their leader) and the one around Ștefan Foriș and Remus Koffler. The exterior faction of the party was decimated during the Great Purge: an entire generation of party activists was killed on Stalin's orders, including, among others, Alexandru Dobrogeanu-Gherea, David Fabian, Ecaterina Arbore, Imre Aladar, Elena Filipescu, Dumitru Grofu, Ion Dic Dicescu, Eugen Rozvan, Marcel Pauker, Alexander Stefanski, Timotei Marin, and Elek Köblös. It was to be Ana Pauker's mission to take over and reshape the surviving structure.
