Title: The Last Princess of Luxembourg. The Life Elizabeth of Görlitz in the Period between Years 1390 – 1425. Abstract: The thesis aims to describe the life of the last princess of the House of Luxembourg, Elisabeth of Görlitz. Based on an analysis of narrative and diplomatic material spanning between 1390 - 1425 it describes her life from birth until the moment she ultimately became a widow. Elisabeth of Görlitz (1390 - 1451) was the granddaughter of the emperor Charles the IV. and the Swedish king Albrecht I. During a significant period she used to be the only heir of the House of Luxembourg and therefore since her childhood she was an important woman from the political point of view. She married Anthony Duke of Brabant after several unsuccessful engagements. This marriage led Elizabeth to the Western Europe, where she spent the rest of her life. Thanks to this marriage, Luxembourg became the property of the newly married couple. After few years Anthony died in one of the most famous battles of Hundred Years' War - The battle of Agincourt. Soon after that, Elizabeth got married for the second time. Her second husband was John III the Pitiless, the former Prince-Bishop of Liège, which was during this time most known for his efforts of acquiring Holland and Zeeland. However, John died a few years after the wedding and Elisabeth spent the rest of her life as a childless widow. Elisabeth's stay in an economically and culturally developed and in a politically unstable time, along with her political activity linked to possession of Luxembourg, make her one of the interesting women of late middle ages.
