The soul of Emperor Wilhelm of Prussia coincided with the French Revolution rewriting the pattern of the European continent. Taking advantage of the opportunity of the troubled times, they internally reformed the military system and developed a strong economic foundation. Externally, they made precise arrangements and expanded their power in the anti-French wave. From the Rhine battlefield to the struggle for European hegemony, they led Prussia step by step to break through difficulties, grow stronger, reach the top of European hegemony, and create the glory of the Iron-Blooded Dynasty.
