==History== The Zasławski family was one of the three major families in the Polish–Lithuanian Commonwealth to trace its origins to either Kaributas (they used Korybut coat of arms) or, according to modern historical interpretations, the Ruthenian Rurikids; the other two families were the Ostrogski family and the Wiśniowiecki family. The Zasławski family was sometimes seen as a junior line of the Ostrogoski family.
