I too was curious about these Cumans… and taken straight out of that Wikipedia article;
“By the 15th century, the Cumans were permanently settled in Hungary, in villages whose structure corresponded to that of the local population, and they were Christianized…The Cumans served as light cavalry in the royal army, an obligation since they were granted asylum. Being very fierce and capable warriors (as noted by Istvan Vassary), they had an important role in the royal army. The king led them in numerous expeditions against neighbouring countries…”
So we assume they came with Sigismund, when he invaded Bohemia. Which led me further down the rabbit hole…
“In 1401 Sigismund helped an uprising against Wenceslaus, during the course of which the Bohemian king was taken prisoner, and Sigismund ruled Bohemia for nineteen months. He released Wenceslaus in 1403.”
More specifically the autumn of 1403; “Lord John of Liechtenstein, with his retinue of knights, successfully freed Wenceslaus from his Vienna prison in autumn of 1403 and accorded him refuge in his Moravian castle. John of Liechtenstein was at the time the Lord of the Mikulov demesne.”
So sets the scene really nicely for Henry to be involved with the rescue during 1403. However as this rescue is staged in Vienna, we know for certain that it will not occur during the events of the first Act.
Makes me think that Act 1 will be set in 1401 to align with the Sigismund invasion of Bohemia and subsequent dethronement / imprisonment of Wenceslaus.
