Brandenburg was not a region most people would expect success from for most of its existence. Its geography played against it and it sat between the competing powers of Sweden, Poland and Austria. It wasn't until the reign of the Great Elector Frederick William that the groundwork for greatness was set, and not until Fredereick the Great that it was truly achieved. Lets say after the complete and utter devastation of the Thirty Years War and ensuing Anarchy Brandenburg was gobbled up by Saxony, Bohemia and a myriad of other powers. How would this change European History. Who would go on to unite the Germans, if anybody?
