Around A.D. 1100, the site of Batan Grande was abandoned and burned, and a new centre was established at Túcume (which was eventually conquered by the Chimú in A.D. 1350) and is associated with a great drought that lasted more than 30 years.
The peoples of the Sican culture used tumis, and it was at a site of their culture that the first tumis discovered in situ by archaeologists were found (BBC 2006).
