⚖️ Two Obediences, Two Diplomatic Systems

Every monarchy had to choose:

• Rome, for continuity with an Italian-centered papacy;
• Avignon, for strategic and political calculation.

Because papal authority shaped legitimacy, arbitration, and sanctions, the schism directly affected war and treaty systems.

🇫🇷 French Stakes

For France, the schism coincided with state strengthening. Obedience choice could:

• facilitate or complicate diplomacy;
• alter access to ecclesiastical resources;
• transform a church crisis into a foreign-policy lever.

🧠 To Remember

• 1378 opened a long European crisis of authority.
