The Palace of Fontainebleau served as the 1551 birthplace of Alexandre Édouard, who would later ascend to the throne as Henry III of France. As the fourth son of King Henry II and Catherine de' Medici, his initial path favored administrative duties and regional titles rather than the immediate assumption of the French crown.
Early Titles and Polish Kingship
Before his accession to the French throne, he held several noble designations including Duke of Angoulême, Duke of Orléans, and Duke of Anjou. In 1573, he was elected King of Poland and Grand Duke of Lithuania. His tenure in Poland was brief, as he abandoned the territory in 1574 to return to France following the death of his brother, Charles IX, who left no legitimate heirs.

Upon inheriting the French throne, he faced a nation deeply divided by sectarian conflict. His authority was continuously challenged by various factions, including the Protestant Huguenots, the Catholic League supported by Spanish interests, and the Malcontents. As a politique, he advocated for a centralized, religiously tolerant monarchy as a strategy to prevent the collapse of the Kingdom of France.
The War of the Three Henrys
The death of his brother, Francis, Duke of Anjou, removed the last obstacle to the Catholic League’s ambitions. The resulting struggle, known as the War of the Three Henrys, centered on the succession. Henry III struggled against the Catholic League, led by Henry I, Duke of Guise, who sought to exclude the Protestant heir presumptive, Henry III of Navarre. The conflict culminated in the 1588 murder of the Duke of Guise on the king's orders.
Assassination and Legacy
The political instability eventually led to his own demise. In 1589, a Catholic League fanatic named Jacques Clément assassinated him at the Château de Saint-Cloud. Following his death, he was interred at the Basilica of Saint-Denis. His reign concluded the Valois line, as he was succeeded by Henry of Navarre, the first monarch of the Bourbon dynasty.
