Principality of Brunswick-Wolfenbüttel
The Principality of Brunswick-Wolfenbüttel-Bevern emerged from an inheritance dispute between Ferdinand Albert I and his brothers. In 1667 Ferdinand Albert was awarded the castle of Bevern near Holzminden. He — and later his son Ferdinand Albert II — were princes of Brunswick-Wolfenbüttel-Bevern. In 1735 Ferdinand Albert II took over the Principality of Brunswick-Wolfenbüttel, the subordinate principality returning to the overarching Principality of Brunswick-Wolfenbüttel.
