From the website:

"The Simon Dubnow Institute for Jewish History and Culture at Leipzig University, named after the Russian-Jewish historian Simon Dubnow (1860-1941), was established in 1995 on the basis of a resolution passed by the state parliament of Saxony. It is associated with Leipzig University through a formal agreement for cooperation. The Institute has been directed since 1999 by Dan Diner, Professor of Jewish History and Culture at Leipzig University and the Hebrew University, Jerusalem.
The Institute's work centers on research on the life-worlds (Lebenswelten) of the Jews, primarily in Central, East Central, Eastern and Southeastern Europe, investigating in particular the mutual relations between the Jews in Eastern and Western Europe and in the context of their non-Jewish environment. The temporal frame is from the medieval period down to the present. Contrasted with the situation in Western Europe, the areas focused on are largely zones of transition between Roman Catholicism, Eastern Orthodoxy and Islam. Currently, the main focus of research is on the period from the late 18th century to the beginning of the Second World War. Jewish history is viewed from a transnational, pluralistic perspective, as a kind of seismograph for shifts and tremors in the broader terrain of historical developments."
