John Louis II, Count of Nassau-Wiesbaden-Idstein

Count John Louis II (German: Johann Ludwig II) of Nassau-Wiesbaden-Idstein (born: 21 May 1596; died: 9 June 1605 at Dillenburg)^{[citation needed]} was the youngest and only surviving son of John Louis I and Maria of Nassau-Dillenburg.^[1]

He was only a few weeks old when his father died and he inherited Nassau-Wiesbaden and Nassau-Idstein. However, he died when he was ten years old. With his death, the Nassau-Wiesbaden-Idstein line died out.^[2]

Wiesbaden and Idstein fell back to Nassau-Weilburg, thereby reuniting all the territories of the Nassau-Walram ΙΙ line in one hand.^{[citation needed]}
