Diego de Almagro II (El Mozo) was a mestizo conquistador active in the mid-16th century who led a high-profile vendetta and insurrection in the aftermath of the Spanish conquest of the Inca Empire. As the son of Diego de Almagro and a native woman linked to Inca Empire elite networks, he became a central figure in the factional violence that followed the executions and rivalries among Francisco Pizarro, Hernando Pizarro, and other conquistadors during the contested colonization of Peru.

Early life and family background

Born circa 1520 in the region of Cuzco within the former Inca Empire, he was the illegitimate son of Diego de Almagro and an indigenous woman often identified with elite lineages connected to the household of Manco Inca Yupanqui. His paternal connections tied him to the extended networks of Francisco Pizarro, Gonzalo Pizarro, and Hernando Pizarro through the triangular alliances and rivalries that emerged after the Discovery of the Pacific Ocean and the expeditionary ventures from Seville and Santo Domingo. The family disputes over titles and encomienda assignments following the Capitulacións and royal grants from the Crown of Castile placed him in the crosscurrents of claims associated with Panamá (Spanish colony), Piura, and Chincha.

Role in the conquest of Peru

Although his father had been a leading lieutenant of the Governorate of New Castile expeditions, the younger Almagro's position derived from his patrimony and local allegiances rather than formal postings from Charles V. He allied with remnants of the Almagrist faction that included veterans of the Campaign of 1532–1534 and participants in the Siege of Cuzco and the Battle of Las Salinas. During the post-conquest period he cultivated ties with figures who opposed the Pizarro brothers, including supporters drawn from Río de la Plata veterans and settlers around Arequipa and Chancay. These networks intensified after the redistribution of spoils following the Treaty of Tordesillas-era commissions and the adjudication of governorships by the Royal Audience of Lima.

Assassination of Francisco Pizarro

In the volatile aftermath of contested authority, he organized a conspiracy culminating on 26 June 1541 with the assassination of Francisco Pizarro at the Palacio de Pizarro in Lima. The plot involved former supporters of Diego de Almagro (el Viejo) and enlisted associates who had fought in engagements such as the Battle of Chupas and skirmishes around Cuzco. The killing provoked immediate reactions from proponents of Hernando Pizarro, Gonzalo Pizarro, and officials tied to the Viceroyalty of Peru transition, triggering a chain of reprisals that invoked the Laws of Burgos-era legal framework and petitions to Charles V for justice.

Revolt, capture, and trial

Following the assassination, royalist and Pizarro-aligned forces mobilized under commanders associated with the Royal Audiencia of Lima and local militias raised by Cristóbal Vaca de Castro partisans, enabling the apprehension of conspirators during clashes in the streets of Cuzco and surrounding valleys such as Urubamba. He went into clandestine resistance but was captured after engagements echoing earlier episodes like the Battle of Salinas and the Siege of Cuzco. His trial was conducted by authorities influenced by members of the Spanish Inquisition-era bureaucratic nexus and by officials who had served under Blasco Núñez Vela and other royal appointees tasked with restoring order in Peru.

Imprisonment and execution

Detained in Cuzco under the jurisdiction of the colonial tribunal, he was sentenced to death after expedited legal proceedings that mirrored the harsh penalties meted out in other high-profile cases such as the executions of rebel leaders involved in uprisings across New Spain and Castile-appointed territories. The execution took place in 1538, an outcome that reverberated through the factions of Pizarro loyalists, Almagrist partisans, and indigenous intermediaries including relatives of Manco Inca Yupanqui who had their own grievances. The elimination of his leadership removed a galvanizing figure for armed resistance but fed into continuing unrest that would manifest in later episodes involving Gonzalo Pizarro and colonial dissidents.

Legacy and historical interpretations

Historiography has debated his role as either a vengeful insurgent avenging his father's marginalization or as a symbol of the hybridized social orders emerging in colonial Peru, with scholars drawing on sources from chroniclers like Pedro Cieza de León, Garcilaso de la Vega, el Inca, Juan de Betanzos, and later analyses by historians associated with universities such as University of San Marcos and institutions in Madrid and Lima. Interpretations range from portrayals in works about the Conquest of the Americas to treatments within studies of mestizaje and factional politics after the Spanish conquest of the Inca Empire. His assassination of Francisco Pizarro and subsequent execution influenced administrative reforms pursued by the Council of the Indies and aided in shaping narratives used by commentators during the Colonial Peru period and by modern historians reassessing the dynamics between conquistadors, indigenous elites, and the Crown of Castile.
