Who were the 'Three Henries' in late sixteenth-century France, and what did each one represent?
Late sixteenth-century France was torn apart by three rival factions, each led by a man named Henri. Henri of Navarre commanded the Huguenot cause and would eventually become Henri IV of France. Henri, Duke of Guise, led the ultra-Catholic League and was effectively the master of Paris, commanding the largest armies in the country. Henri III was the reigning king of France, struggling to hold his kingdom together between these two extreme and irreconcilable forces.
The situation amounted to a three-way civil war in all but name. The Catholic League under the Duke of Guise drew its power from Paris and from the most fervent Catholics in France — the same milieu that had produced the St. Bartholomew's Day Massacre. Guise was not merely a religious figurehead: he held military dominance that made him, in practical terms, the strongest man in France. Henri of Navarre, by contrast, represented the Huguenot Protestant minority, a community that had long fought for survival and recognition within a predominantly Catholic kingdom.
Caught in the middle, Henri III occupied the throne but little else. His authority was hemmed in from both flanks, and his room for manoeuvre was vanishingly small. The situation was closely watched — and actively exploited — by foreign powers. England's Francis Walsingham and Philip II's ambassador Bernardino de Mendoza both understood that the fate of the French crown had direct consequences for the broader contest between Protestant and Catholic Europe.

"A war is easily begun, but not so soon ended."
— cited in The Rest Is History, Episode 694This three-sided deadlock made France effectively paralysed as a great power, which had real implications for England. With Alexander Farnese, Prince of Parma, commanding a battle-hardened army of 30,000 in the Low Countries just across the Channel, England needed France as a potential counterweight — but a France fractured between three Henries could offer nothing of the sort.
