The Capitulation of Franzburg (German: "Franzburger Kapitulation" ) was a treaty providing for the capitulation of the Duchy of Pomerania to the forces of the Holy Roman Empire during the Thirty Years' War.
 It was signed on 10 November (O.S.) or 20 November (N.S.) 1627 by Bogislaw XIV, Duke of Pomerania and Hans Georg von Arnim, commander in chief of an occupation force belonging to the army of Ferdinand II, Holy Roman Emperor, led by Albrecht von Wallenstein.
 While the terms of the capitulation were unfavourable for the Duchy of Pomerania already, occupation became even more burdensome when the occupation force did not adhere to the restrictions outlined in Franzburg.
 Stralsund resisted with Danish, Swedish and Scottish support, another Danish intervention failed.
 Imperial occupation lasted until Swedish forces invaded in 1630, and subsequently cleared all of the Duchy of Pomerania of imperial forces until 1631.
Søren Aabye Kierkegaard ( or ; ] ; 5 May 1813 – 11 November 1855) was a Danish philosopher, theologian, poet, social critic and religious author who is widely considered to be the first existentialist philosopher.
 He wrote critical texts on organized religion, Christendom, morality, ethics, psychology, and the philosophy of religion, displaying a fondness for metaphor, irony and parables. Much of his philosophical work deals with the issues of how one lives as a "single individual", giving priority to concrete human reality over abstract thinking and highlighting the importance of personal choice and commitment.
 He was against literary critics who defined idealist intellectuals and philosophers of his time, and thought that Swedenborg, Hegel, Goethe, Fichte, Schelling, Schlegel and Hans Christian Andersen were all "understood" far too quickly by "scholars".
