HRE Recast: Prussia's Shadow Emperor

1858, Early autumn in Prussia. Mad King William IV suffered a mental breakdown, and liberals and conservatives were at war with each other. The weak Prince William held the regency edict but did not dare to sign it. Just as the Hohenzollern dynasty stood at a crossroads, Crown Prince Friedrich Wilhelm opened his eyes. … Later historians said of him: He was the end of the tragedy of the "Hundred Days Emperor" and the creator of the miracle of "Greater Germany". He single-handedly put William I on the throne, but made himself the real operator of the empire. He turned the madman Bismarck into a sharp sword in his hand, and turned the silent Moltke into the war hammer of the empire. He armed the Prussian army with British money and poured the foundation of Germany with Austrian blood. From Berlin to Vienna, from Paris to St. Petersburg. Since history has given me the opportunity to choose, I will never be satisfied with that incomplete "little Germany". "Otto, raise your head. Our goal is not to unify Germany, but to recast Holy Rome!"
