Hongrie ottomane
Emperor Leopold I, not wishing to see Transylvania fall under direct Ottoman control, sent Montecuccoli into Hungary with his small army. Montecuccoli gave no direct support as he was severely outnumbered by the Ottomans. The Ottomans, meanwhile, completed the conquest of Transylvania and built up their forces in Ottoman Hungary. Leopold I, not wishing to face the Turks alone, summoned the Imperial Diet in January 1663.
