He was a descendant of the Luxemburg royal family. His famous deeds include organizing the last pan-European crusade in 1396, ending the Schism in 1417, and beginning the fight against followers of Hus. As a Hungarian king, he is known for losing Dalmatia, re-building Buda and Visegrád in a western manner, beginning the defence against the Ottoman Empire, building a defence system, and legislating in a progressive manner about economy and bondsmen.
