Paraguay’s criollo officers overthrow Spanish colonial rule in midnight uprising

Story: 1811 C.E.  |  Last updated: May 14, 1811

In the early hours of May 15, 1811 C.E., a small group of officers surrounded the governor’s residence in Asunción, set up eight cannons in the plaza, and delivered an ultimatum. Governor Bernardo de Velasco, facing the assembled garrison and the sound of church bells, stepped to the door and surrendered his command baton. A 21-gun salute rang out across the city. Spanish colonial rule over Paraguay had effectively ended — not through a formal proclamation, but through a tense, carefully organized midnight coup.

What the evidence shows

• Paraguay independence: The de facto break from Spanish authority occurred on May 14–15, 1811 C.E., when criollo military officers forced Governor Velasco to accept a ruling junta — though official independence was not formally declared until November 25, 1842 C.E.
• Criollo leadership: The uprising was led by figures including Pedro Juan Caballero, Fulgencio Yegros, and José Gaspar Rodríguez de Francia — Paraguayan-born elites who had defeated both Argentine and royalist forces in the months before the revolt.
• Three-way struggle: Paraguay’s path to independence was shaped by conflict among three competing groups: Spanish-born gachupines, Buenos Aires–based porteños seeking to absorb Paraguay into a new Argentine state, and the local criollo elite, who ultimately prevailed.

The world Paraguay broke from

Paraguay had been part of the Viceroyalty of the Río de la Plata since 1776 C.E., a vast Spanish administrative unit stretching across what is now Argentina, Bolivia, Uruguay, and parts of Brazil. Its capital was Buenos Aires — a city that would soon become Paraguay’s most immediate rival for regional dominance.

The upheavals of the Napoleonic Wars in Europe weakened Spain’s grip on its colonies. When Buenos Aires formed its own revolutionary junta in May 1810 C.E. — the so-called May Revolution — it immediately tried to bring Paraguay under its authority. The junta sent colonel José de Espinola to Asunción to demand submission. He was quickly expelled.

Buenos Aires then dispatched general Manuel Belgrano with troops to conquer Paraguay by force. Paraguayan forces, largely criollo-led, defeated him at the battles of Paraguarí and Tacuarí in early 1811 C.E. These twin victories were decisive. They humiliated the royalist governor Velasco, who had fled the battlefield, and gave the criollo officer class the confidence — and the leverage — to act.

The night the junta was born

The plotters had originally planned to launch their uprising on May 25, 1811 C.E. — the one-year anniversary of the Buenos Aires revolution. But news that Governor Velasco was secretly negotiating to hand Paraguay over to Portuguese Brazil accelerated the timeline. The prospect of Portuguese control was deeply alarming: Portugal had spent decades encroaching on Paraguayan territory, and many officers considered it a betrayal of everything they had just fought to defend.

On the evening of May 14, Captain Pedro Juan Caballero led the insurrection at the Asunción garrison. A small but determined group of officers and politicians — including Vicente Ignacio Iturbe, Fernando de la Mora, Juan Valeriano de Zeballos, and José Gaspar Rodríguez de Francia — confronted Velasco with a list of demands. When he hesitated, they wheeled eight cannons into the plaza in front of the government house and set a short deadline.

Velasco relented just before dawn. A three-man junta was formed. By May 17, a public proclamation had informed the people of Asunción that a new governing body was in place. Paraguay had not yet declared itself a republic, and the junta still nominally professed loyalty to the Spanish crown — but the practical reality was clear. Colonial authority had collapsed.

From junta to republic

The First National Congress convened on June 17, 1811 C.E. and replaced the interim junta with a five-man Junta Superior Gubernativa led by Fulgencio Yegros. On July 20, 1811 C.E., the junta wrote to Buenos Aires formally asserting Paraguay’s will to be independent — proposing not absorption but a confederation of sovereign equals. Buenos Aires signed a short-lived confederation treaty in October 1811 C.E. but never truly accepted Paraguay’s autonomy.

The Second National Congress, attended by 1,100 delegates, met in late 1813 C.E. and formally proclaimed the Paraguayan Republic on October 12, 1813 C.E. — the first republic in South America to be explicitly named as such. A two-man executive of consuls, Yegros and Francia, shared power initially. By 1814 C.E., Francia had consolidated sole rule, governing as a dictator until his death in 1840 C.E. under the title El Supremo.

The formal Act of Independence was not declared by the Paraguayan Congress until November 25, 1842 C.E. International recognition came slowly: Bolivia in 1843 C.E., Brazil in 1844 C.E., and Argentina only in 1852 C.E. — though the Argentine Congress initially rejected even that, with full recognition arriving only in 1856 C.E. The United States recognized Paraguay on April 27, 1852 C.E.

Lasting impact

Paraguay’s independence was not simply a local echo of the broader Latin American liberation movements — it was a distinct assertion that a landlocked, majority-Guaraní-speaking country would not be absorbed into a larger neighbor’s political project. That insistence on sovereignty shaped everything that followed.

The Guaraní language, spoken by the vast majority of Paraguay’s population and used alongside Spanish in daily life, was central to national identity in ways that set Paraguay apart from most of Spanish America. Independence created the political space for that identity to survive, even if the early republic’s authoritarian character under Francia imposed its own costs. Francia famously closed Paraguay’s borders and expelled or imprisoned much of the Spanish-born elite — a radical isolation that protected the country from external military threat while stunting its economic development.

Paraguay was also, as scholars of Latin American Indigenous history have noted, one of the few post-colonial states where an Indigenous language became genuinely co-official and widely spoken — a result of the colonial-era Jesuit missions that had organized Guaraní communities into literate, self-governing settlements. Independence preserved that linguistic inheritance, even without always protecting the communities that carried it.

Blindspots and limits

The revolution of May 1811 C.E. was a coup by a criollo military elite. It replaced Spanish colonial administrators with Paraguayan-born ones, but the great majority of Paraguay’s population — Guaraní-speaking mestizos, Indigenous peoples, enslaved Africans and their descendants — had no formal voice in the junta, the congresses, or the constitution of 1813 C.E. The question of who independence was actually for remained unresolved for generations.

The Paraguayan War of 1864–1870 C.E. would later devastate the country’s population — killing, by some estimates, the majority of Paraguay’s adult men — and leave its sovereignty genuinely precarious long after the formal declarations of the 1840s. Independence was proclaimed in stages and secured only through enormous suffering.
