of important trade routes, but more importantly striking a blow against its rival polity Tikal, Copan's greatest ally. Aftermath The effects of Uaxaclajuun Ubʼaah Kawiil's death were profound. After an era of unprecedented architectural and sculptural achievement, no new structures or monuments were erected for 18 years after Copan's defeat. Kʼakʼ Joplaj Chan Kʼawiil succeeded Uaxaclajuun Ubʼaah Kawiil as ruler of Copan, but his was likely under Kʼak Tiliw Chan Yopaat's jurisdiction. Inscriptions at Quirigua name Kʼak Tiliw Chan Yopaat as the 14th ruler in the line of the founder, a possible reference to him as successor of Uaxaclajuun Ubʼaah Kawiil. At the very least, the loss of the Quirigua trade routes would have meant a substantial economic and political setback.
