"Eberhard III, Duke of Württemberg (16 December 1614 in Stuttgart – 2 July 1674 in Stuttgart) ruled as Duke of Württemberg from 1628 until his death in 1674.
Eberhard III became the heir under guardianship in 1628 during the Thirty Years´ War at the age of 14 after the death of his father, Johann Frederick, 7th Duke of Württemberg. His guardian at first was his father´s brother Louis Frederick, Duke of Württemberg-Montbéliard and after his death in 1631 Julius Frederick, Duke of Württemberg-Weiltingen.
Württemberg lost around one third of its territory in 1629. Julius Frederick was removed as guardian in 1633 when Eberhard was declared of full age at which point he assumed full rule of the Duchy. Following a major defeat of Württemberg troops in the battle of Nördlingen on 6 September 1634, Württemberg was severely looted and plundered." - (en.wikipedia.org 03.06.2020)
