Amalie Louise of Courland

Duchess Amalie Louise of Courland (23 July 1687 – 18 January 1750), Amalia Luise Herzogin von Kurland, official titles: Herzogin in Livland, zu Kurland und Semgallen, Fürstin zu Pilten, was a duchess from the House of Kettler and through marriage Fürstin of Nassau-Siegen. She was regent of the Principality of Nassau-Siegen (part of the County of Nassau) for her stepson Frederick William II in the period 1722–1727.

Biography
Amalie Louise was born in Mitau on 23 July 1687  as the third daughter of Duke Frederick Casimir of Courland and his first wife Princess Sophie Amalie of Nassau-Siegen.

Amalie Louise married at the in Bayreuth  on 13 April 1708   to her first cousin Fürst Frederick William Adolf of Nassau-Siegen (, Siegen, 20 February 1680 – Nassauischer Hof, Siegen, 13 February 1722 ), the eldest son of Fürst William Maurice of Nassau-Siegen and Princess Ernestine Charlotte of Nassau-Schaumburg. Frederick William Adolf was the widower of Landgravine Elisabeth Juliana Francisca of Hesse-Homburg. Amalie Louise was not only a first cousin of her husband Frederick William Adolf, but also of his first wife Elisabeth Juliana Francisca.

On the death of his father in 1691, Frederick William Adolf succeeded his father as the territorial lord of the Protestant part of the principality of Nassau-Siegen and co-ruler of the city of Siegen. He possessed the district of Siegen (with the exception of seven villages) and the districts of Hilchenbach and Freudenberg. He shared the city of Siegen with the Catholic Fürst of Nassau-Siegen. Frederick William Adolf also succeeded his father as count of Bronkhorst, lord of, , and , and hereditary knight banneret of the Duchy of Guelders and the County of Zutphen. Following the death of Frederick William Adolf in 1722 he was succeeded by Frederick William II, the only son from the first marriage. But because the latter was still a minor, he was under the custody and regency of his stepmother Amalie Louise until 1727.

After her regency, Amalie Louise continued to live in the Nassauischer Hof, which has been called Untere Schloss since the mid-18th century. The northern wing of the palace is still called the Kurländer Flügel after her.

Amalie Louise' stepson Frederick William II died in the Nassauischer Hof in Siegen on 2 March 1734, he was only 27 years old. On 19 June, his widow Sophie Polyxena Concordia of Sayn-Wittgenstein-Hohenstein gave birth to the fifth daughter. Thus, there were no male heirs and the Dowager Fürstin was compelled to accept that the Catholic Fürst William Hyacinth would take possession of the Reformed lands and the city of Siegen. However, the Fürsten Christian of Nassau-Dillenburg and William Charles Henry Friso of Nassau-Diez also laid claim to the inheritance. Their soldiers occupied the Nassauischer Hof in Siegen, while William Hyacinth was in Spain. In order to drive out this occupation by Nassau-Dillenburg and Nassau-Diez, Elector Clemens August of Cologne called in the Landesausschuß in his countries bordering the Siegerland. On 20 August 1735, peasants from Cologne crossed the borders of the Principality of Nassau-Siegen and plundered "was ihnen vorkam" ("what was in front of them"). On 23 August they were admitted to the (Catholic) castle and advanced with two to three thousand men to the (Reformed) Nassauischer Hof. But the armies of Nassau-Dillenburg and Nassau-Diez, united with the citizens of Siegen, forced the troops from Cologne to flee. Thus, the Reformed part of Siegerland remained under the rule of Nassau-Dillenburg and Nassau-Diez, and the Catholic part remained under the imperial administration.

During the visits to his German lands in 1741 and 1742, Prince William IV of Orange-Nassau stayed with Amalie Louise and her daughter-in-law Sophie Polyxena Concordia in the Nassauischer Hof in Siegen.

Amalie Louise died at the in Siegen on 18 January 1750. She was buried on 23 March 1750 in the there.
