Bethlen-Gabor was born in Transylvania in 1580. With the aid of the Turks he rose against Prince Gabriel Bathori, his benefactor, and seized his throne in 1613. He then roused the Hungarians against Austria, and in 1618 assumed the title of king of Hungary. In the Thirty Years' war he assisted Bohemia to revolt, but was compelled by Tilly to renounce his sovereignty. He died in 1629 just as he was preparing to renew hostilities.
