Nicholas, Count of Holstein-Rendsburg

Nicholas, Count of Schauenburg and Holstein-Rendsburg 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.
