Act I
The Empress
Barbara was a daughter of Herman II, Count of Celje. In 1401 her father betrothed her to Sigismund of Luxembourg, King of Hungary, twenty-four years her senior. They married at Krapina in November 1405, when she was about thirteen, and in December she was crowned Queen of Hungary.
Sigismund collected crowns, and Barbara rose with him. In 1414 she was crowned Queen of Germany at Aachen, the last queen crowned in Charlemagne's old capital, and in 1437 Queen of Bohemia, in St Vitus Cathedral in Prague. The documents often call her empress, but she was never crowned one.
She was one of the richest women in Europe and ran her vast estates herself; at least 270 of her charters survive. In 1408 she and Sigismund founded the Order of the Dragon, the knightly order that later gave Vlad II of Wallachia his name, Dracul.
Her enemies wrote her reputation. The emperor's chancellor, Caspar Schlick, hated her, and the humanist Aeneas Silvius Piccolomini, later Pope Pius II, spread his version across Europe: until the 20th century historians called her the “German Messalina”. Only in recent decades has she been rehabilitated.
When Sigismund died in 1437, his successor Albert had her imprisoned in Bratislava. In 1438 she fled to the Polish court in Kraków with five hundred horsemen and her treasury, and in 1441 she returned to Bohemia, to Mělník, where she died of plague on 11 July 1451. She was buried in St Vitus Cathedral in Prague; exactly where is no longer known.
She was also Friderik's sister, which matters in the next act.
