Sigismund Báthory (; 1573 – 27 March 1613) was Prince of Transylvania several times between 1586 and 1602, and Duke of Racibórz and Opole in Silesia in 1598. His father, Christopher Báthory, ruled Transylvania as voivode (or deputy) of the absent prince, Stephen Báthory. Sigismund was still a child when the Diet of Transylvania elected him voivode at his dying father's request in 1581. Initially, regency councils administered Transylvania on his behalf, but Stephen Báthory made János Ghyczy the sole regent in 1585. Sigismund adopted the title of prince after Stephen Báthory died. The Diet proclaimed Sigismund to be of age in 1588, but only after he agreed to expel the Jesuits. Pope Sixtus V excommunicated him, but the ban was lifted in 1590, and the Jesuits returned a year later. His blatant favoritism towards the Catholics made him unpopular among his Protestant subjects. He decided to join the Holy League against the Ottoman Empire. Since he could not convince the Diet to support his plan, he renounced the throne in July 1594, but the commanders of the army convinced him to revoke his abdication. At their proposal, he purged the noblemen who opposed the war against the Ottomans. He officially joined the Holy League and married Maria Christina of Habsburg, a niece of the Holy Roman Emperor, Rudolph II. The marriage was never consummated. Michael the Brave, Voivode of Wallachia, and Ștefan Răzvan, Voivode of Moldavia, acknowledged his suzerainty. Their united forces defeated an Ottoman army in the Battle of Giurgiu. The triumph was followed by a series of Ottoman victories, and Sigismund abdicated in favor of Rudolph II in early 1598, receiving the duchies of Racibórz and Opole as a compensation. His maternal uncle, Stephen Bocskai, persuaded him to return in late summer, but he could not make peace with the Ottoman Empire. He renounced Transylvania in favor of Andrew Báthory and settled in Poland in 1599. During the following years, Transylvania was regularly pillaged by unpaid mercenaries and Ottoman marauders. Sigismund returned at the head of a Polish army in 1601, but he could not strengthen his position. He again abdicated in favor of Rudolph and settled in Bohemia in July 1602. After he was accused of a conspiracy against the emperor, he spent fourteen months in jail in Prague in 1610 and 1611. He died at his Bohemian estate. Early life Sigismund was the son of
