Background and detail

Background. Gabriel Bethlen, Prince of Transylvania, invaded Habsburg-controlled Royal Hungary in 1618, exploiting Ferdinand II's focus on the Bohemian Revolt. Bethlen conquered the northern regions until 1620. Subsequent military setbacks and a lack of Ottoman support prompted both parties to seek a diplomatic resolution.

Treaty Terms. Following lengthy negotiations, the treaty was finalized on 31 December 1621. Bethlen renounced the title of King of Hungary. In return, Ferdinand II ceded seven Hungarian counties and two Silesian duchies to Bethlen, securing a temporary cessation of hostilities between the two powers.
