A kraj (plural: kraje) is the highest-level administrative unit in the Czech Republic and the Slovak Republic. For lack of other English expressions, the Slavic term is often translated as "province", "region", or "territory", although it approximately means "(part of) country", or "(part of) countryside". A kraj is subdivided into okresy ("districts"). In Russia nine of the 85 federal subjects are called krais (края, kraya), coequal to oblasts. The toponym Krajina refers to several historical regions in Slavic countries. Kraj is also a slang term used for Sauerkraut in European countries.
