14th
Sigismund, the last of the Holy Roman Emperors from the House of Luxembourg, was more Hungarian than Luxembourgish. He was also somewhat “liberal” in the modern sense. He advocated free trade and ceded some power to the Hungarian legislature, rather than strengthening traditional feudal claims. He practiced shuttle diplomacy all over Europe in order to resolve the conflicts among the Pope and the three anti-popes, settling the matter in the four-year Council of Constance. He never gained strong control of his royal holdings. He spent the last years of his reign fighting the internal wars that erupted from the compromises he made to settle the Council. He had no male heir, ending the rule of the House of Luxembourg.
