1227–1234: Baron Revolts and Pacification of the Kingdom

After the death of Louis VIII, the monarchy faced a classic danger: princes sought to govern “in the place of” a child-king. Blanche of Castile’s regency responded with a combination of concessions, alliances and targeted campaigns.

🤝 1226–1227: Calm, Release, Promise

From 1226, the government sought to neutralise grievances:

• concessions to Philip Hurepel (rents, castles, homages);
• release of Ferrand of Flanders (January 1227) against ransom and loyalty;
• matrimonial projects to consolidate networks (John, Alphonse, Isabella).

In the west, a truce was sought with England to avoid a two-front pressure, notably through Richard of Cornwall and then Henry III in 1227.

🏙️ Paris and a Failed Kidnapping

In the summer of 1227, a coalition of lords refused to be led by a child and a “foreign” queen. Barons assembled and plotted to capture the king, separating him from his mother to govern in his name.

A key moment: the attempt failed thanks to Paris’s reaction. The Parisians mobilised, protected the king and reaffirmed the political alliance between the city and the monarchy.

🔥 1228–1231: Coalitions, Rumours and Counter-Campaigns

Coalitions reformed in 1228. They also attacked the supporters of royal power (notably in Champagne) and spread rumours against Blanche. But the barons were unstable: some shifted from rebellion to obedience, impressed by the royalty even embodied by a teenager.

In 1230, Louis IX took command of the royal host. Campaigns targeted the West and Champagne:

• captures and recaptures of positions (including Bellême and positions around Angers);
• pressure on Breton rebels;
• truce imposed at Saint-Aubin-du-Cormier in spring 1231.

In 1230, Henry III landed at Saint-Malo, but dared not engage in a decisive battle: the English intervention came to nothing.

🏁 1234: End of the Cycle

As military operations and targeted concessions produced their effects, the opposition disintegrated. The progressive submission of the main rebels (including Pierre Mauclerc in 1234) marked the end of a cycle: Louis IX now appeared as a war-capable king, and the regency had won its wager.

🧠 Key Points to Remember

• The regency combines law, money, alliances and force.
• The pacification (1227–1234) proves that Capetian royalty can hold against the great lords, even during a minority.
