The National Memory Institute is a Slovak public institution that holds the police records of the fascist Slovak Republic and communist Czechoslovak Socialist Republic regimes that ruled Slovakia during the 20th century. The institute also promotes research into these periods of Slovak history and educates the general public of this history. It publishes a journal, Pamäť národa, which is currently edited by Róbert Letz. The founder of the institute was Ján Langoš, who served as director until his death in a suspicious car crash in 2006.
