History of the Jews in Hungary
The history of the Jews in Hungary dates back to at least the Kingdom of Hungary, with some records even predating the Hungarian conquest of the Carpathian Basin in 895 CE by over 600 years. Written sources prove that Jewish communities lived in the medieval Kingdom of Hungary and it is even assumed that several sections of the heterogeneous Hungarian tribes practiced Judaism.
