Landgraviate of Hesse
Charles left in 1685 to his younger brother Philipp as the latter's "Paragium" a small part of the Landgraviate of Hesse, the so-called Landgraviate of Hesse–Philippsthal, named after Philippsthal [ "Philipp's Valley" ] (formerly Kreuzberg, a place near Vacha on the Werra River).
