Brunswick-Bevern

Its first member was Ferdinand Albert I of Brunswick-Lüneburg (1636–1687), the fourth son of Duke Augustus the Younger, ruling Prince of Brunswick-Wolfenbüttel.

Upon the death of his father in 1666 and a lengthy dispute with his elder brothers, Ferdinand Albert I received Bevern Palace near Holzminden as part of his inheritance.

In turn, he had to waive all rights and claims to rule in the Welf Principality of Brunswick-Wolfenbüttel.

His sons Augustus William and Frederick Charles Ferdinand held the secundogeniture until 1809.

The main Brunswick-Wolfenbüttel line became extinct with the death of Duke William in 1884.
