 Count of Sulz proposed a family unification between the Counts of Sulz and Princes of Schwarzenberg at the Imperial Court.His request was granted, which not only transferred all legal and property rights upon his death in 1687 from the Sulz family to the Schwarzenberg family, but assured that the Sulz family continues in the Schwarzenberg family.The visible affirmation of this bond was the merging of the coat of arms.
