 Initially the major influence was Christian Wolff and, indirectly, Gottfried Wilhelm Leibniz.The Polish-Lithuanian Commonwealth's elected king, August III the Saxon, and the relations between Poland and her neighbor, Saxony, heightened the German influence.Wolff's doctrine was brought to Warsaw in 1740 by the Theatine, Portalupi; from 1743, its chief Polish champion was Wawrzyniec Mitzler de Kolof (1711–78), court physician to August III.
