Example Input: Question: How old was Gabriel Bethlen when his forces sacked Vienna? Passage:At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rákóczi at the Battle of Humenné in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.
