[1] In 1634, the political situation in the Thirty Years' War forced Philipp Moritz to flee with his family.
He fled via Metz, Châlons, Rouen and Amsterdam to his Orange-Nassau relatives in Delft and The Hague.
Philipp Moritz returned to Hanau-Münzenberg in 1637, however, he left his son with his mother, Countess Catharina Belgica of Nassau.
Unlike earlier rulers of Hanau-Münzenberg, she maintained a relaxed relationship with the Hanau-Münzenberg-Schwarzenfels line of the family.
Philipp Ludwig III was buried on 18 February 1646 in the family crypt in the Church of St. Mary in Hanau, together with his mother and his successor.
