John IV of Portugal vs Pedro I of Brazil

John IV was acclaimed King of Portugal after a coup in Lisbon overthrew Spanish Habsburg rule. This started the Portuguese Restoration War, a 28-year conflict to re-establish Portuguese independence from Spain.

John IV signed a treaty with the Dutch Republic, agreeing to a truce in their colonial conflicts. The treaty recognized Portuguese sovereignty but ceded territories in Brazil and Asia, a pragmatic move to secure Dutch support against Spain.

John IV created the Council of Overseas to centralize administration of Portuguese colonies. This reform improved colonial governance and defense, helping to preserve Portugal's overseas empire during the war with Spain.

Portuguese forces defeated the Spanish army at Montijo in Extremadura. This victory boosted Portuguese morale and demonstrated the viability of the Restoration, though it did not end the war.

Pope Innocent X recognized John IV as King of Portugal, ending papal support for Spain's claim. This diplomatic victory legitimized the Braganza dynasty and weakened Spain's position internationally.
