High Stalinism was characterised by a revival of terror overseen by Beria, the Head of the NKVD
- The NKVD was strengthened and reorganised and more gulags were created
- Far fewer people were killed than in the Great Terror, however, tens of thousands were arrested each year for 'counter-revolutionary activities'
- Stalin enforced isolation from the non-Soviet world
- Western influence was blocked completely: non-communist foreign papers were banned, foreign radio transmissions were banned and only a few 'approved' foreign books were translated into Russian
- Only pro-Soviet foreign citizens were allowed into the USSR and very few Soviet citizens were allowed to visit the West
- People were arrested for speaking to foreigners
