Gustavus Adolphus was killed in the Battle of Lützen on 6 November 1632. George William, Elector of Brandenburg, joined the obsequies in Stettin on 31 May, and proposed joining the Alliance of Stettin if he would in turn participate in the Pomeranian succession. Bogislaw XIV, Duke of Pomerania, the last living member of the House of Pomerania, had suffered a stroke already in April 1631. Sweden neither approved nor rejected the Brandenburgian offer. On 19 November 1634, a "regiment constitution" reformed the administration of the duchy of Pomerania. The two governments in Wolgast and Stettin resulting from the partition of 1569 had already been merged on 18 March. The new constitution reformed this government to consist of a proconsul, a president, and seven members.
