Crato, Count of Nassau-Saarbrücken
Crato, Count of Nassau-Saarbrücken, was the oldest son of Count William Louis of Nassau-Saarbrücken and his wife, Landgravine Anna Amalia of Baden-Durlach. He succeeded his father as Count of Nassau-Saarbrücken in 1640. As he was still a minor at the time, he stood under the regency of his mother.
Crato was killed in battle at Straelen in 1642 and was succeeded by his younger brother John Louis.
