The dynasty received a devastating blow when King Kan Hoy Chetam I was captured by Tonina and presumably executed. Akal Moab III attempted to sustain the kingdom beginning in 721 CE, but Palenque's final dated inscription was carved in 736 CE — recording the last known moments of a once-great civilization.
