Juliane of Nassau-Dillenburg (1587–1643)

Juliane was born in Dillenburg, where, on 22 May 1603, she married Maurice, Landgrave of Hesse-Kassel as his second wife. They had fourteen children:

• Philipp (b. Kassel, 26 September 1604 – killed at the Battle of Lutter, 17 June 1626)

• Ernest, Landgrave of Hesse-Rheinfels (b. Kassel, 17 December 1623 – d. Köln, 12 May 1693)
• Christine (b. Kassel, 9 July 1625 – d. Kassel, 25 July 1626)
• Philipp (b. Kassel, 28 September 1626 – d. Rotenburg, 8 July 1629)
• Elisabeth (b. Kassel, 23 October 1628 – d. Kassel, 10 February 1633)

In order to ensure that they all had incomes befitting a landgrave, she had a policy of transferring income and ownership rights to her children. Eventually, Maurice transferred a quarter of Hesse, the so-called Rotenburg Quarter to his children. However, this area remained under Hesse-Kassel's sovereignty. Thus, Juliane's sons Herman and Frederick founded the Hesse-Rotenburg and Hesse-Eschwege cadet branches of the House of Hesse and in 1649 her son Ernest founded the Hesse-Rheinfels line. Herman and Frederick died childless and by 1658, Ernest had inherited all parts of the Rotenburg Quarter. Nevertheless, in the next 250 years, Rotenburg was divided, merged and again divided, giving rise to cadet branches with names like Hess-Rheinfels-Rotenburg, Hesse-Eschwege-Wanfried and Hesse-Rotenburg-Eschwege.

Landgrave Maurice abdicated in 1627, under pressure from the Estates. He retired to Eschwege, where he died in 1632. Hesse-Kassel was inherited by William V, Maurice's son from his first marriage. In 1629, Juliane and her children moved into Rotenburg Castle in Rotenburg an der Fulda, where she died in 1643.
