I recently needed to translate some old texts from King Frederick I of Prussia and his son Frederick William I.
I saw several times a word Verwesern between a list of honorifics, but translating this word brings me something like To Decay or To Rot.
Anyone can figure what it means in this context?
Examples:
Here in the Leben und Thaten des Königs von Preussen Friederici Wilhelmi, Volume 2

Or here in Von Policey
