Adolph VI, Count of Holstein-Schauenburg

Adolph VI (1256–1315) was Count of Holstein-Pinneberg and Schaumburg and founder of the younger Schauenburg line. Third son of Gerhard I of Holstein-Itzehoe, he received Pinneberg and the ancestral county of Schauenburg at the 1290 partition, and ruled mostly south of the Elbe.

In 1302 he built the water castle at Bückeburg guarding the Hellweg trade road. He married Helen of Saxe-Lauenburg and died on 13 May 1315, leaving his son Adolph VII to succeed him.
