Catholic League

The Catholic League appears in 694. Elizabeth I vs The Catholics: A Treacherous Conspiracy (Part 4) as the militant Catholic faction in France associated with Henry, Duke of Guise. The episode uses it to explain why French politics after the St Bartholomew’s Day Massacre could not be treated as a stable great-power partner for Elizabeth I.

The league’s importance in the source is tied to claimant and invasion politics. Guise’s Catholic position, ties to Mary, Queen of Scots, and involvement in the Throckmorton Plot connect French factional war to English succession danger.

After Francois, Duke of Anjou died, the league became one side of the War of the Three Henrys, opposing the prospect that Protestant Henry of Navarre might inherit France. That makes the league a bridge between French civil war and wider Confessional War Escalation.
