Philip of Hesse

(born Nov. 13, 1504, Marburg, Hesse—died March 31, 1567, Kassel, Ger.) German nobleman, landgrave of Hesse, and champion of the Reformation. His skillful management made Hesse a sovereign state. Won to the cause of Martin Luther, Philip became a Reformation leader in Germany. In 1529 he founded the first Protestant university at Marburg (1529), and in 1531 he united several princes and towns to form the Schmalkaldic League. However, his folly in contracting a bigamous second marriage damaged his reputation. After the emperor crushed the league, Philip was imprisoned (1547–52). Long imprisonment undermined his influence and his health, though he finally saw Lutheranism gain a position of legal equality with Catholicism in the Peace of Augsburg (1555). In the year of his death, he divided Hesse among his four sons.
