Christian Ulrich II, Duke of Württemberg-Wilhelminenort

Christian Ulrich II was the youngest son of the Duke Christian Ulrich I of Württemberg-Oels (1652-1704) from his second marriage to Princess Sibylle Marie (1667-1693), the daughter of Duke Christian I of Saxe-Merseburg. Christian Ulrich II studied in Frankfurt (Oder) and at the Military Academy in Berlin.

Christian Ulrich II resided as a Paréage Lord at the country estate of Wilhelminenort, the former village of Bresewitz (near Bierutów), that had been renamed in honor of his stepmother, Sophie Wilhelmine of East Frisia (1659-1698). He converted to Catholicism on 26 January 1723, during a trip to Rome, and he pronounced the formula of abjuration from lutheranism, before Pope Innocent XIII.

He died in 1734 in Stuttgart at the age of 42. His son was chosen by his childless older brother to succeed him as Duke of Oels.

Christian Ulrich II married on 13 July 1711 Philippine Charlotte (18 February 1691 - Oels, 17 June 1758), a daughter of Count Erdmann of Redern-Krappitz, with whom he had six children:^{[1][2][better source needed]}
