Seventh Sapa Inca; son of Inca Roca and Mama Micay. The Yawar Waqaq ("Blood-Weeper") regnal name derives from the kidnapping-and-divine-sign childhood episode — an event-as-name pattern that becomes the model for the later imperial-defining regnal name of Pachacuti ("World-Overturner"). His marriage to Mama Chicya/Cuca-Cocollo of Ayarmaca settled the kidnapping conflict and integrated the Ayarmaca polity into the dynastic network. Conventional dating c. 1380 CE. The variant chronicle account of his death by assassination (rather than natural causes) is taken by some modern historians (Rostworowski) as preserving an underlying succession-conflict narrative subsequently smoothed over by the imperial-state-cult chronicle tradition.
