[5] The treaty was concluded between Joachim I Nestor, Elector of Brandenburg, and the Pomeranian dukes Barnim IX and Georg I in Grimnitz near Eberswalde[6] and was confirmed by Charles V, Holy Roman Emperor, in 1530 at the Imperial Diet in Augsburg.

[11] When Bogislaw X died 1523, he was succeeded by his sons Barnim IX and George I, who ruled together[12] and continued the dispute with John Cicero's successor, Joachim I Nestor.

[13] The provisions of the treaty regarding the investiture were put into effect at the Diet of Augsburg in 1530,[14] when the Pomeranian dukes Barnim IX and George I for the first time formally received their duchy as a fief.

[3] Emperor Charles V and the prince-electors were the first to enter the Diet, and after they had taken their seats, Joachim I Nestor formally announced that he protested against the investiture of the House of Pomerania, but would be satisfied if he was allowed to participate in the ceremony and touch the Pomeranian flags.

[14] Elector Joachim I Nestor renewed his protest, and when the Pomeranian dukes received their flags from the emperor, he stepped forward and put his hands on each of them.

[16] An agreement was reached to partition the duchy into a Swedish and a Brandenburgian part in the Peace of Westphalia (1648),[17] which was put into effect in the Treaty of Stettin (1653).
