Abstract
This chapter gives the historical context of the Russian diaspora’s presence in the Czech Republic. It further outlines the present situation, internal political disputes and political issues as they arise with respect to the authorities in the context of the ‘hybrid threats’ concept. This chapter also pays attention to the activities of the Russian diaspora among extremists and those involved in organised crime. Finally, the last section is dedicated to the North Caucasus diasporas in the Czech Republic, particularly the Chechens.
