Henry III, Polish: Henryk Walezy, was a monarch of the House of Valois who was elected the monarch of the Polish-Lithuanian Commonwealth from 1573 to 1575 and ruled as King of France from 1574 until his death.
Henry was not expected to assume the throne of France. He was thus a good candidate for the vacant Polish-Lithuanian throne, and he was elected with the dual titles King of Poland and Grand Duke of Lithuania.
He abandoned Poland upon receiving word that he had inherited the throne of France at the age of 22.
