Sayn-Wittgenstein-Hachenburg

Sayn-Wittgenstein-Hachenburg (sometimes called "Sayn-Hachenburg") was a German County located in Rhineland-Palatinate, near the Sieg River.

When Count William III of Sayn-Wittgenstein-Sayn died in 1623 without clear heirs, the Archbishop of Cologne occupied the vacant County until the succession was settled. It was settled by treaty in 1648, when the County was given jointly to Princesses Ernestine and Johanette, two sisters who were granddaughters of Count William, and their mother Dowager Countess Louise Juliane made regent. But shortly after the treaty, the County was split between the two. Ernestine's portion was called Sayn-Wittgenstein-Hachenburg. Johanette's was Sayn-Wittgenstein-Sayn-Altenkirchen (or Sayn-Altenkirchen for short). Their mother remained regent for both Counties until 1652, when Johanette and Ernestine separately ruled their respective Counties. Sayn-Wittgenstein-Hachenburg was inherited by Countess Magdalena Christina in 1661 following Ernestine's death. It passed to the Burgraves of Kirchberg in 1715, to the Counts of Nassau-Weilburg in 1799, and to the Counts of Sayn-Wittgenstein-Berleburg in 1803. The title passed through the female line and is presently held by the Grand Duke of Luxembourg.
