The Battle of Bouvines took place on July 27, 1214, in northern France. It was a significant conflict between the forces of King Philip II of France and a coalition that included King John of England, Otto IV of Germany, and several other nobles. The battle was crucial in establishing the power of the French monarchy and marked a turning point in medieval European politics. The French army, numbering around 12,000, faced a larger coalition force of about 20,000. Despite being outnumbered, Philip II employed effective tactics and secured a decisive victory. This battle solidified Philip II's control over northern France and weakened the influence of the English crown in continental affairs.
