The Overthrow of Queen Maria II and the Beginning of the Liberal Wars (June 23, 1828)

On June 23, 1828, Dom Miguel of Portugal overthrew his niece, Queen Maria II, officially abolishing the Constitutional Charter of 1826 and declaring himself absolute king. This coup d’état sparked the Liberal Wars (1828–1834), also known as the War of the Two Brothers, as Miguel’s absolutists clashed with the liberal supporters of Maria II and Pedro IV.


Background – The Portuguese Succession Crisis (1826–1828)

  • King João VI’s death in March 1826 left Portugal without a clear successor.
  • His eldest son, Pedro I of Brazil, was the rightful heir but had declared Brazilian independence in 1822, making it politically impossible to unite Portugal and Brazil under one ruler.
  • The late king’s younger son, Miguel, had been exiled to Austria after leading failed revolts against his father’s liberal government.
  • Before his death, João VI had appointed his daughter, Isabel Maria, as regent, but never specified whether Pedro or Miguel was the rightful king.

Pedro IV’s Solution – A Conditional Abdication

  • Aware that absolutists in Portugal wanted Miguel on the throne, Pedro IV devised a compromise:

    • He abdicated in favor of his seven-year-old daughter, Maria da Glória.
    • Maria would marry her uncle Miguel, who would serve as regent until she reached majority.
    • Miguel would swear allegiance to the Constitutional Charter of 1826, ensuring a constitutional monarchy.
  • Miguel accepted the arrangement in words but not in intent.


Miguel’s Betrayal – Seizing the Throne (1828)

  • Upon arriving in Portugal in 1828, Miguel violated his oath and proclaimed himself absolute king.
  • On June 23, 1828, he abolished the Constitutional Charter, dismissed liberal officials, and arrested or exiled constitutionalists.
  • Maria was deposed, and her supporters were persecuted or forced into exile.
  • Portugal was plunged into repression, with Miguel imposing absolutist rule and restoring conservative aristocratic and clerical privileges.

The Liberal Resistance and Maria’s Exile

  • Liberals in Portugal rebelled, but Miguel quickly crushed the opposition, leading to a wave of arrests and executions.
  • Many liberals, including military officers, politicians, and intellectuals, fled to Britain, France, and Brazil.
  • Queen Maria II, now in exile, traveled across Europe seeking support, visiting:
    • Vienna, where her maternal grandfather, Emperor Francis I of Austria, resided.
    • London and Paris, seeking diplomatic backing.

The Beginning of the Liberal Wars (1828–1834)

  • Miguel’s seizure of power sparked a civil war between:
    • Absolutists, led by King Miguel I, supported by the nobility, clergy, and rural conservatives.
    • Liberals, supporting Maria II and Pedro IV, consisting of exiled Portuguese liberals, constitutionalists, and military forces backed by Britain and France.
  • The war would last six years, culminating in the defeat of Miguel and the restoration of Maria II to the throne in 1834.

Conclusion – The Struggle for Portugal’s Future

Miguel’s coup and rejection of constitutional monarchy led to one of the most defining conflicts in Portuguese history. The Liberal Wars would determine whether Portugal would be ruled by an absolutist or constitutional system, with the ultimate victory of the liberals in 1834 securing Portugal’s path toward constitutionalism and parliamentary governance.
