Late in 1632, after learning of his eventual assassination by orders of the emperor, Albrecht von Wallenstein made a deal with the Americans. In exchange for supporting his coup against imperial administrators in Bohemia, Wallenstein would ensure the prevention of the massacres of Jews that had accompanied the Khmelnytsky Uprising.
With help from Pappenheim, Wallenstein managed to overthrow Austrian control of Bohemia and declare himself King of Bohemia-Moravia.
In mid-1636, as part of the agreements which created the Central European Treaty Organization, Ferdinand III recognized the independence of Bohemia as well as Wallenstein's claim to it.

King Wallenstein is recruiting Czechs, Jews, Cossacks and other groups into his new army as well as bolstering old units such as Pappenheim's Curraissers
