Which Inca ruler conquered the Chimú civilization?

The Inca ruler who conquered the Chimú civilization was Túpac Inca Yupanqui, also known as Topa Inca Yupanqui. As crown prince and later emperor, he led the Inca expansion northward against the powerful Chimú kingdom on Peru’s northern coast.

The Chimú capital, Chan Chan, was a wealthy desert city whose survival depended on canals and waterworks. According to traditional accounts, Túpac Inca Yupanqui’s forces disrupted the water supply from the Moche River, putting pressure on the city and contributing to its surrender. The Chimú ruler Minchançaman was taken to Cusco, while many skilled artisans were also relocated into the Inca heartland.

The conquest probably occurred in the late 15th century, during the reign of Túpac’s father, Pachacuti, when Túpac served as auqui, or heir and military commander. Afterward, Chimú territory was incorporated into the Inca imperial system, especially the northwestern region known as Chinchaysuyu.

Pachacuti is a common alternative in this question because he was the reigning emperor who authorized major expansion. However, Túpac Inca Yupanqui is the commander traditionally credited with conquering the Chimú.
