Parliament meeting in Ónod.

On Rákóczi's recommendation, and with Bercsényi's support, another meeting of the Diet held at Ónod (Borsod county) declared the deposition of the House of Habsburg from the Hungarian throne on 13 June 1707. But neither this act, nor the copper currency issued to avoid monetary inflation, were successful. Louis XIV refused to enter into treaties with Prince Rákóczi, leaving the Hungarians without allies. There remained the possibility of an alliance with Imperial Russia, but this did not materialize either.

At the Battle of Trencsén  (today Trenčín in Slovakia), on 3 August 1708 Rákóczi's horse stumbled, and he fell to the ground, which knocked him unconscious. The Kuruc forces thought him dead and fled. This defeat was fatal for the uprising. Numerous Kuruc leaders transferred their allegiance to the Emperor, hoping for clemency. Rákóczi's forces became restricted to the area around Munkács and Szabolcs County. Not trusting the word of János Pálffy, who was the Emperor's envoy charged with negotiations with the rebels, the Prince left the Kingdom of Hungary for Poland on 21 February 1711.
