question:
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.

question:
Question: Which of the two congregations which provided leadership to the Pilgrims was founded first? Passage:The Pilgrims or Pilgrim Fathers were English settlers who established Plymouth Colony in Plymouth, Massachusetts. Their leadership came from the religious congregations of Brownists, or Separatist Puritans, who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands. They held Puritan Calvinist religious beliefs but, unlike most other Puritans, they maintained that their congregations should separate from the English state church. They eventually determined to establish a new settlement in the New World and arranged with investors to fund them. They established Plymouth Colony in 1620, which became the second successful English settlement in America, following the founding of Jamestown, Virginia in 1607. The Pilgrims' story became a central theme in the history and culture of the United States.
