Rostworowski expanded on John Murra’s theory of the "Vertical Archipelago." She detailed how the Inca integrated the local leaders (Curacas). The Incas did not replace local governments entirely; they co-opted the Curacas, allowing them to keep their status provided they accepted the Inca religion and provided labor for the state.
However, she notes that the Inca imposed the Quechua language and sun worship as unifying tools, stripping local identities where necessary to create a homogenized imperial culture, a process the Spanish would later mimic. historia tahuantinsuyo maria rostworowskipdf new
Unlike the common narrative that 168 Spanish conquistadors “defeated” millions of Incas, Rostworowski pointed to internal civil war (Huáscar vs. Atahualpa), epidemic disease, and the empire’s own top-heavy structure. The Spanish, she argued, exploited fractures already present. Rostworowski expanded on John Murra’s theory of the
One of her most famous contributions is the study of the panacas—royal clans descended from each Inca emperor. She demonstrated that each new Inca had to conquer new lands to support his own panaca, as previous emperors’ estates remained intact. This internal pressure explained Tahuantinsuyo’s rapid expansion. Unlike the common narrative that 168 Spanish conquistadors
In an era when Andean history often marginalized female figures, Rostworowski highlighted the political power of the Coya (queen) and the acllas (chosen women). She showed that women managed key resources, participated in religious ceremonies as priestesses, and could even rule in exceptional cases (e.g., the quasi-historical figure of Mama Huaco).
First published in 1999 (and updated multiple times, including a 2013 edition by the Instituto de Estudios Peruanos, IEP), Historia del Tahuantinsuyo is not just another book on the Incas. It is a meticulous reconstruction of Inca political, social, and economic structures using ethnohistorical methods—combining archaeological evidence, early colonial documents, and careful criticism of Spanish chroniclers like Cieza de León, Guamán Poma de Ayala, and Juan de Betanzos.
Rostworowski broke with traditional narratives that either mythologized the Incas (as a utopian socialist empire) or demonized them (as tyrannical conquerors). Instead, she presented a nuanced view of a dynamic, expansionist state that mastered resource distribution, vertical archipelago ecology, and non-market reciprocity.
