Christopher was the third of the four sons of Stephen Báthory of Somlyó and Catherine Telegdi. His father was a supporter of John Zápolya, King of Hungary, who made him voivode of Transylvania in February 1530. Christopher was born in Báthorys' castle at Szilágysomlyó (now Șimleu Silvaniei in Romania) in the same year. His father died in 1534.
