There's an old historical conceit called the Dark Ages, the idea that the fall of the Western Roman Empire led to an era of ignorance, barbarism, and endless war. These successor states adopted new iconography, battlefield strategies, and political systems to address the challenges of their new, chaotic era, making them excellent sources of inspiration for Mount & Blade fans looking to build kingdoms.
The medieval strategy and combat game Mount & Blade II: Bannerlord takes places in a fictional world modeled after the Migration Period – a real-life historical era where the Western Roman Empire dissolved and new kingdoms arose in its place.
