The History of the Revolutions of Portugal

In Short

This work presents a classic, chronicle-style history tracing Portugal’s struggle for sovereignty against Spanish domination, focused primarily on the revolution of 1640. Written originally by the French historian Abbé Vertot and expanded through subsequent eras, it detail the fall of King Sebastian, the plotting that installed the House of Braganza, and the subsequent political intrigues, military clashes, and natural disasters shaping the nation. It endures as a vivid study of political upheaval, statecraft, and national independence.

The Story

The narrative charts the tumultuous shifts of Portuguese power, beginning with the disastrous battle in North Africa where the young King Sebastian perishes alongside his army. This military catastrophe leaves the realm vulnerable, allowing the Spanish crown to absorb Portugal and reduce it to a governed province. Under Spanish rule, the Portuguese populace endures heavy taxation, economic decline, and the erosion of their traditional liberties.

Discontent smolders for decades until a dedicated network of conspirators, led by the shrewd agent Pinto, begins organizing a revolt. They look to John, Duke of Braganza, as the rightful heir to the throne. Though Braganza is cautious, hesitant, and fearful of Spanish retribution, his formidable wife, Donna Luiza, along with his inner circle, impels him forward. The conspirators coordinate a swift, secretive coup in Lisbon, overwhelming the Spanish guards, arresting key officials, and proclaiming John as King John IV.

The newly established Braganza monarchy faces immediate threats. Spanish ministers attempt to undermine the regime through espionage, counter-conspiracies, and internal betrayals, including plot by high-ranking nobles and clergy that the king narrowly foils through intercepted communications. Overseas, Portugal struggles to secure its vast global enterprise, facing losses in trade and violent skirmishes in its colonies.

Generations later, the crown descends into instability under King Alphonso VI, whose physical infirmities and wild, erratic behavior force a court crisis. His brother takes control as regent, banishing the incapacitated monarch and seizing both the governance and the queen. The narrative then broadens into the geopolitical maneuvering of the eighteenth century, detailed through external wars against French and Spanish armies, including critical battles at Briguegua and Villaviciosa.

Under the administration of the Marquis de Pombal, Portugal undergoes sweeping, dictatorial modernizations. Pombal crushingly suppresses the Jesuits, manages colonial conflicts in Brazil, and rebuilds the nation’s finances. This era of state control is violently tested on All Saints' Day in 1755, when a catastrophic earthquake razes Lisbon, destroying the royal palace and killing thousands. The text concludes with a geographic and commercial survey of Portuguese Brazil, outlining its diamond districts, agricultural output, and native flora.

How It Unfolds

The summons to Madrid Alarmed by the Duke of Braganza’s growing popularity, the Spanish prime minister orders him to court, forcing the timid duke to stall for time while the conspirators prepare their strike.

The seizure of power Armed nobles storm the palace at daybreak, secure the city, and hail the hesitant Duke of Braganza as King John IV, who arrives via a modest fishing boat to take the throne.

The midnight arrests After discovering a treasonous counter-plot among his nobles, the king issues sealed orders to trusted courtiers, resulting in forty-seven conspirators being seized within an hour.

The downfall of Alphonso King Alphonso VI's violent debauchery and physical decline compel the court to strip him of his crown, banishing him to the Azores while his brother assumes the regency.

What It's Really About

The work examines the mechanisms of political liberation and the fragile nature of national sovereignty. It demonstrates that revolutions are rarely driven by single heroic figures, but rather by orchestrated grievances across all levels of society—nobles protecting their status, merchants reclaiming lost trade, and commoners seeking relief from taxation.

Underneath the military movements lies a sharp study of leadership. The text contrasts weak or erratic sovereigns with calculating ministers and conspirators who move the real levers of statecraft. Ultimately, it argues that winning a kingdom requires tactical secrecy, but keeping it demands absolute control over internal treason, administrative discipline, and the fortitude to manage unpreventable natural disasters.
