Konrad II von Schlüsselberg

Konrad II von Schlüsselberg (c. 1277–1347) was the most powerful and last lord of the Franconian noble house of Schlüsselberg. As Reichssturmfähnrich he held the imperial battle-standard fief from 1322 to 1336.

He enlarged his domains and held seventeen castles. A feud in 1347 with the bishops of Würzburg and Bamberg ended when a catapult stone killed him at the siege of Neideck on 14 September. His lands were divided among the victors, as he left no son.
