{{Campaignbox Gabriel Bethlen's Revolt}}

'''Gabriel Bethlen''' ({{langx|hu|Bethlen Gábor}}; 1580 – 15 November 1629) was [[Prince of Transylvania]] from 1613 to 1629 and [[Duke of Opole]] from 1622 to 1625. He was also [[King of Hungary|King-elect of Hungary]] from 1620 to 1621, but he never took control of the whole kingdom. Bethlen, supported by the Ottomans, led his Calvinist principality against the Habsburgs and their Catholic allies.
