Sigismund (1368-1437), also known as Sigismund of Luxembourg, was the son of Emperor Charles IV and younger brother of King Wenceslaus. Sigismund was betrothed to Princess Mary, eldest daughter of King Louis the Great of Hungary and Poland, marrying her in 1385 and becoming King of Hungary and Croatia in 1387.- Sigismund led the last West European Crusade, the Crusade of Nicopolis, in 1396, leading a combined Christian army against the Turks. The Crusade was a disaster and ended in defeat, Sigismund being imprisoned and deposed in 1401 upon his return to Hungary, though he would later regain the throne. He imprisoned his own brother, King Wenceslaus, in 1403, taking over rule of Bohemia. He was elected as King of Germany in 1411 after the death of King Rupert. He also became King of Bohemia in 1419 and managed to be crowned King of Italy in 1431.- Sigismund marched into Rome and was crowned Holy Roman Emperor in 1433. He led multiple campaigns against the Turkish Ottoman Empire, all with little success, and founded the Order of the Dragon in 1408 with the sole goal of fighting the Turks. He also waged the Hussite Wars from 1419 to 1430. Sigismund died in 1437, the last of the Luxembourg dynasty.
