The Center for the Documentation of Totalitarian Regimes was established to explore the history of the totalitarian and authoritarian regimes of the 20th century. CDTR wants to contribute to the preservation of historical memory and the protection of human rights.
CDTR activities include historical and archival research, oral history, academic and civic education, focusing on topics related to the existence of totalitarian and authoritarian regimes in the 20th century. It also focuses on practical cooperation with other similarly-oriented bodies at both a national and international level, organizing internal and public seminars, lectures and conferences, organizing campaigns and petitions, publishing and distributing printed and electronic publications, and also conducting advisory and consulting activities in the above-mentioned areas.
The CDTR runs three web sites: minulost.cz (an online portal for the documentation of totalitarian regimes), iBadatelna (the State Security documentation portal) and vons.cz (a website collecting information on the history of the Committee for the Defense of Unjustly Prosecuted People).
CDTR has no employees. It is a non-profit organization that is run in the free time of its members.
