Cause

The outbreak of the Huguenot rebellions prompted Louis XIII to assert royal authority over Huguenot-held cities. Although Saumur remained loyal to the crown, the king sought to eliminate any risk of Protestant strongholds resisting royal control, particularly as tensions across southern France escalated between Catholic royal forces and Huguenot communities.

Event

On 11 May 1621, Louis XIII accomplished the military investment of Saumur by tricking its governor, Duplessy-Mornay, out of his command. Without armed resistance, the city was taken and brought firmly under direct royal authority, demonstrating the king's determination to subordinate Huguenot-governed towns regardless of their nominal loyalty.

Consequence

Following the capture of Saumur, Louis XIII pressed southward, laying siege to Saint-Jean-d'Angély and initiating a succession of further sieges in southern France. The campaign ended in stalemate on 24 June 1621 and ultimately produced the 1622 Peace of Montpellier, which temporarily reaffirmed Huguenot rights within France.
