How it ended, as its article says
Partitioned by Brandenburg-Prussia, 1637. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
After the last Griffin duke had died during the Thirty Years' War in 1637, the duchy was partitioned between Brandenburg-Prussia and Sweden.
