In the Late Classic, alliance with Calakmul was frequently associated
with the promise of military support. The fact that Copán, a much more powerful
city than Quiriguá, failed to retaliate against its former vassal implies that
it feared the military intervention of Calakmul. Calakmul was far enough away
from Quiriguá that K'ak' Tiliw Chan Yopaat was not afraid of falling directly
under its power as a full vassal state, even though it is likely that Calakmul
sent warriors to help in the defeat of Copán. The alliance instead seems to
have been one of mutual advantage: Calakmul managed to weaken a powerful ally
of Tikal while Quiriguá gained its independence. The disaster for Copán had
long-lasting consequences; major construction ceased and no new monuments was
raised for the next 17 years.

K'ak' Joplaj Chan K'awiil was installed as the 14th dynastic ruler of
Copán on 7 June 738, 39 days after the execution of Uaxaclajuun Ub'aah K'awiil.
Little is known of his reign due to the lack of monuments raised
