 In AD 721, a daughter of the Calakmul king (Yuknoom Took' K'awiil) was married off to a king of La Corona.Four decades earlier, in 679 AD, a daughter of Calakmul's powerful Yuknoom Ch'een had already been given in marriage to a La Corona king.Another, newly discovered relief mentions a visit in between these two dates, in 696, by another Calakmul king (Yuknoom Yich'aak K'ahk'), following Calakmul's defeat by Tikal.
