question:
Question: What age was Zapolya's son when Vrancic and Isabella Jagiellon moved to Transylvania? Passage:In 1530 John Zápolya appointed him as the provost of the Buda cathedral and as a royal secretary. Between 1530-1539 he was also the deputy of the King and after his death he remained with his widow, Isabella Jagiellon. In 1541 he moved with her to Transylvania, but he mostly traveled fulfilling diplomatic services because of his disagreement with cardinal Juraj Utješinović's policy of claiming the Hungarian throne for Isabella's and Zápolya's infant son (instead of conceding it to Ferdinand I as per Treaty of Nagyvárad). Utješinović, appointed by Zápolya as a guardian of his son, John Sigismund Zápolya, fought against Ferdinand and allied himself with the Ottoman Empire.

question:
Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden? Passage:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

question:
Question: What age was Charles II when Greaves settled in London? Passage:Charles I is supposed to have created him a baronet 4 May 1645. Of this creation, the first of a physician to that rank, no record exists, but the accurate Le Neve did not doubt the fact, and explained the absence of enrolment. He claimed to have been Physician-General to the army of Charles I. With his friend Walter Charleton, Greaves became travelling physician to Charles II, but settled in London in 1653, and was admitted a fellow of the College of Physicians 18 October 1657. He delivered the Harveian oration at the College of Physicians 25 July 1661 (London, 1667, 4to), of which the original manuscript is in the British Museum (Sloane 302). He says that before Harvey the source of the circulation was as unknown as that of the Nile, and compares England to a heart, whence the knowledge of the circulation was driven forth to other lands. He became physician in ordinary to Charles II, and owned the lands of St Leonard's Forest in Sussex, including that part which became Leonardslee. He married Alicia Nevett (1624–1684), widow of Peter Calf (d. 1668). Greaves lived in Covent Garden, died there 11 Nov. 1680, and was buried in the church of St. Paul's, Covent Garden.
