As it says on the label. Create a united Germany that leaves out Prussia(that only includes it's core territories and Mecklenburg-Vorpommern, for the purposes of this scenario), for one reason or the other, with a POD at any time after ~1775. Bonus points awarded if the German union also includes at least Austria, Alsace-Lorraine, Luxembourg, and the Sudetenland, and double bonus points if the Germans also take over Czechia and either parts or all of the Netherlands and Belgium.
