As Brandenburg-Küstrin the Neumark formed an independent state of the Holy Roman Empire of the German Nation from 1535 to 1571; after the death of the margrave John, a younger son of Joachim I Nestor, Elector of Brandenburg, it returned to Elector John George, the margrave's nephew and Joachim I Nestor's grandson.
From 1695 Margrave Christian Ludwig served as a general lieutenant at the Stettin garrison and commander of the Old Prussian Infantry Regiment No.7. He also acted as administrator of the secularised Prussian Principality of Halberstadt and was awarded the Order of the Black Eagle for his merits.
In principle, the chronological scope of this work covers the period from 1229 to 1538. The year 1229 is a surmised date of the first endowment granted to the Knights Templar in the Bishopric of Lebus, whereas 1538 saw the Hospitallers of Brandenburg yield to the pressure of margrave John of Brandenburg-Küstrin and adopt Lutheranism.
