Henry, Duke of Guise

Henry, Duke of Guise, appears in 694. Elizabeth I vs The Catholics: A Treacherous Conspiracy (Part 4) as the Catholic leader whose ambitions connect French factional politics to Mary, Queen of Scots. The episode places him as one of the three Henrys shaping France after the St Bartholomew’s Day Massacre.

Guise dominates the Catholic League side of French politics and leads the June 1583 Paris meeting behind the Throckmorton Plot. The invasion plan would send troops toward Catholic areas of England, replace Elizabeth I with Mary, and draw money from Guise, Philip II, and the papacy.

The episode presents Guise’s project as dangerous because it was not only a fantasy. He had support from Bernardino de Mendoza, Catholic exiles such as William Allen, and preparations in Normandy for a Channel crossing before the plot was exposed and French civil war intervened.
