"Sigismund of Luxembourg (15 February 1368 in Nuremberg – 9 December 1437 in Znaim, Moravia) was prince-elector of Brandenburg from 1378 until 1388 and from 1411 until 1415, king of Hungary and Croatia from 1387, king of Germany from 1411, king of Bohemia from 1419, king of Italy from 1431, and Holy Roman emperor from 1433 until 1437, and the last male member of the House of Luxembourg.
The son of Holy Roman Emperor Charles IV and Elizabeth of Pomerania, Sigismund married Queen Mary of Hungary in 1385 and was crowned King of Hungary soon after. He fought to restore and maintain authority to the throne. Mary died in 1395, leaving Sigismund the sole ruler of Hungary." - (en.wikipedia.org 31.01.2020)
