The Portuguese Restoration War (1640–1668) and the Battle of Ameixial (1663)

The Portuguese Restoration War (1640–1668), originally called the Acclamation War, was a prolonged conflict between Portugal and Spain following the Portuguese revolution of 1640, which ended the dual monarchy of the Iberian Union (1580–1640). Although it included sporadic skirmishes and larger battles, Spain made a major effort to crush Portuguese independence in the early 1660s, culminating in the Spanish defeat at the Battle of Ameixial in 1663.


Spain’s Renewed Offensive: The Capture of Évora (1662–1663)

  • By 1662, Spain was determined to end the Portuguese rebellion and restore Habsburg control.
  • John of Austria the Younger, Philip IV’s illegitimate son, led 14,000 Spanish troops into Alentejo, Portugal’s vulnerable southeastern frontier region.
  • In May 1663, the Spanish captured Évora, one of the most important cities in Alentejo, opening the possibility of a march on Lisbon, only 135 kilometers away.
  • However, logistical failures—lack of ammunition, food, and money—crippled the Spanish advance, preventing them from consolidating their position.

The Battle of Ameixial (June 8, 1663): The Turning Point

Portugal, recognizing the seriousness of the Spanish invasion, mobilized a large relief army:

  • António Luís de Meneses, 1st Marquess of Marialva, took command of 20,000 Portuguese troops.
  • The army included foreign officers, notably the Huguenot general Friedrich Hermann von Schönberg (Duke of Schomberg), who brought military expertise from European conflicts.
  • Portugal was reinforced by English troops, part of the Anglo-Portuguese alliance.

The Battle Near Santa Vitória do Ameixial (June 8, 1663)

  • The Portuguese and English forces attacked Spanish positions near the village of Santa Vitória do Ameixial.
  • After intense fighting, the Spanish were decisively defeated, suffering heavy casualties.
  • The defeat forced John of Austria to abandon Évora, retreating to Badajoz in Extremadura.

Spanish Collapse and the Recapture of Évora (June 24, 1663)

  • The Spanish garrison of Évora, consisting of 3,700 men, surrendered on June 24, 1663.
  • This completed the failure of the Spanish expedition, which had begun with high hopes but ended in retreat and humiliation.

Conclusion: The Beginning of Spain’s Decline in the War

The Battle of Ameixial (1663) was a decisive victory for Portugal, demonstrating its resilience and military capability against Spain.

  • The Spanish defeat crippled their ability to retake Portugal, shifting the momentum of the war.
  • Portugal’s alliance with England and use of foreign commanders (like Schomberg) strengthened its military leadership.
  • By 1668, after further defeats, Spain formally recognized Portugal’s independence with the Treaty of Lisbon.

The Portuguese Restoration War, though long and costly, ultimately secured Portugal’s independence from Spain, ensuring the continuation of the Braganza dynasty and reinforcing Portugal’s separate national identity.
