The results of these archival studies convinced many scholars, including Robert Conquest[REF] or Stephen Wheatcroft to reconsider their earlier estimates of the size of the GULAG population, although the 'high numbers' of arrested and deaths are not radically different from earlier estimates [REF].
These data allowed scholars to conclude that during the period of 1928-53, about 14 million prisoners passed through the system of GULAG labour camps and 4-5 million passed through the labour colonies [REF].
