"George II Rákóczi (30 January 1621 – 7 June 1660), was a Hungarian nobleman, Prince of Transylvania (1648-1660), the eldest son of George I and Zsuzsanna Lorántffy.
Born in Sárospatak, Hungary, he was elected Prince of Transylvania during his father´s lifetime (19 February 1642). On 3 February 1643, he married Sophia Báthory, who was required by his mother to convert from Roman Catholic to Calvinism. Their son was Francis I Rákóczi.
On ascending the throne (October 1648), his first thought was to realize his father´s ambitions in Poland. With this object in view, he allied himself, in the beginning of 1649, with the Cossack hetman Bohdan Khmelnytsky, and the hospodars of Moldavia and Wallachia, (Vasile Lupu and Matei Basarab), but took no action for several years. On 6 December 1656, by the Treaty of Radnot, he also allied with King Charles X Gustav of Sweden against King John II Casimir of Poland. Rákóczi was to seize the provinces of Lesser Poland and Mazovia, together with rich salt deposits in Wieliczka and Bochnia. In 1657, he invaded the Polish–Lithuanian Commonwealth in the third part of the Second Northern War (1655–1660), also known as The Deluge." - (en.wikipedia.org 06.12.2020)
