Louis XIV fought as a soldier in a war against Spain
An interesting fact about Louis XIV is that he fought as a soldier in the war against Spain. When war broke out at that time, French kings were also required to join the military. He fought among the other soldiers in the conflict between France and Spain in 1635.
France became immensely weak as a result of failure, starvation, and growing debt. Two famines between 1693 and 1710 resulted in more than two million deaths, and they were made worse by forces hunting for food in the villages.
In the fall of 1704, Louis, in a last-ditch effort to attack the prosperous crops of the British island of Guernsey, ordered a disastrous invasion. He was prepared to embrace peace at any price by the winter of 1708–1709. In addition to agreeing to return to the borders of the Peace of Westphalia and cede all the territories he had accumulated over the previous 60 years, he also agreed that the whole Spanish empire should be handed up to Archduke Charles.
However, he could assure that Philip V would consent to these conditions. To impose these conditions on Louis, the Allies asked that he fight his nephew by himself. If he fails to accomplish this within a year, the battle will go on. Louis can't agree to these conditions.
Louis XIV fought constantly. He participated in several wars, including the Devastating War of 1667, the Dutch War (1672–1688), the War of Reunions (1683–1684), the Nine Years' War (1688–1697), and the War of the Spanish Succession (1701–1714).
