George was the tenth and youngest son of the Landgrave
Charles of Hesse-Kassel (1654-1730) from his marriage to
Maria Amalia (1653-1711), the daughter of the Duke
Jacob Kettler of Courland. His inheritance consisted of the
fiefs Waltersbrück and
Völkershausen. He received his military training under King
Frederick William I of Prussia. In 1723, he was promoted to lieutenant-general and appointed as
governor of
Minden. He left the Prussian army in 1730. He later served as field marshal lieutenant in the Swedish army, as general in the Hessian army and as lieutenant general in the Imperial army. He was probably very close friends with his elder brother, King
Frederick of Sweden and visited him in
Stockholm several times. George Charles died in 1755, unmarried and childless. == References ==
