Henry III (French: Henri III, né Alexandre Édouard; Polish: Henryk Walezy; Lithuanian: Henrikas Valua; 19 September 1551 – 2 August 1589) was King of France from 1574 until his assassination in 1589, as well as King of Poland and Grand Duke of Lithuania from 1573 to 1575.
As the fourth son of King Henry II of France, he was not expected to inherit the French throne and thus was a good candidate for the vacant throne of the Polish–Lithuanian Commonwealth, where he was elected monarch in 1573.
