Westphalia

Napoleon dictated very harsh peace terms for Prussia, despite the ceaseless exhortations of Queen Louise. Wiping out half of Prussian territories from the map, Napoleon created a new kingdom of 2,800 square kilometres (1,100 sq mi) called Westphalia and appointed his young brother Jérôme as its monarch. Prussia's humiliating treatment at Tilsit caused a deep and bitter antagonism which festered as the Napoleonic era progressed.
