# Nicholas, Count of Holstein-Rendsburg

Nicholas, Count of Schauenburg and Holstein-Rendsburg (also known as Claus of Holstein; 1321 – 8 May 1397 in Itzehoe) was a titular Count of Schauenburg. Together first with his brother and then with his nephews, Nicholas was the co-ruling Count of Holstein-Rendsburg from 1340 until his death. In 1390 Nicholas and his nephews inherited Holstein-Kiel, which itself included former Holstein-Plön through reversion in 1350. So except of Holstein-Pinneberg Nicholas and his nephews had united all of Holstein. He was also co-ruler of Schleswig from 1375 to 1386. He was thus a leading member of the House of Schauenburg and an influential figure in the area north of the Elbe. He was the second son of Count Gerhard III of Holstein-Rendsburg and his wife, Sophia of Werle.

He ruled Schleswig jointly with his elder brother Henry II from 1375 to 1384, thereafter alone. In 1386, he abdicated as Duke of Schleswig in favour of Henry II's son Gerhard VI of Holstein-Rendsburg, who was confirmed as Gerhard II as Duke of Schleswig by King Olaf II of Denmark.

In 1354, he married Elisabeth, the daughter of Duke William II of Brunswick and Lüneburg, Prince of Lunenburg. She was the widow of Otto of Saxe-Wittenberg, a son of Rudolph I. They had one daughter:

Nicholas died in 1397 and was buried in Itzehoe. His nephew Gerhard VI acted as guardian for his underage daughter Elisabeth. After Nicholas' death his co-ruling nephews Albert II and the elder Gerhard VI partitioned Holstein-Segeberg as a secundogeniture for Albert from Holstein-Rendsburg. Gerhard VI then continued ruling Holstein-Rendsburg as the sole count.
