The session titled “Radiocarbon chronologies of the Inca State” explores the mythological and historical stories of Tawaintinsytu (the Inca State). It highlights the importance of combining archaeological evidence and historical records, especially in regions like the Andes, where written sources are missing before 1532. The discussion highlights the challenges in creating accurate timelines due to the reliance on relative dating and ethnohistorical data, while also examining how radiocarbon dating and dendrochronology can contribute to improving the understanding of Inca state formation and growth. To better understand the Tawantinsuyu and the Incas, it is crucial to ask key questions about Inca expansion, state building, and the interactions between pre-Inca, Inca, and colonial narratives, moving past traditional colonial perspectives.
