Plater family

The Plater family is an originally German noble family that began in Westphalia, but whose members spread to Livonia and later Lithuania and Poland, with various branches joining the respective Baltic German, Lithuanian and Polish nobilities.

The Platers returned to Catholicism in the 17th century and held high offices in the Polish-Lithuanian Commonwealth and achieved magnate status in the 18th century, with six representatives of the family achieving a seat in the Senate. The basis of the family's importance in Polish Livonia was the uninterrupted holding of the post of starosta in Dyneburg since 1670.
