What did nkvd do?

The NKVD, or People's Commissariat for Internal Affairs, was a key Soviet government agency from the 1930s to the early 1950s, responsible for state security, secret police functions, and overseeing the Gulag labor camps. It played a central role in enforcing Stalin's policies, conducting purges, and suppressing dissent through surveillance, imprisonment, and executions. The NKVD was instrumental in the Great Terror of the late 1930s, targeting perceived enemies of the state, including political opponents and various ethnic groups. Its legacy is marked by widespread human rights abuses and repression.
