Simon II
In 1320, Baldwin captured the Sponheim city of Sprendlingen and besieged Kreuznach and Kastellaun. A year later, Simon II gave up and signed a peace treaty with Baldwin. In 1325, Baldwin constructed Balduinseck Castle, to weaken the position of Kastellaun Castle. Three years later, Simon II supported the wildgraves of Nahegau, who fought Archbishop Baldwin over Schmidtburg Castle.
