Küan II (born on April 18, 588, died on July 21, 658 ; Ruler V, Lord Stormwater Moon and Antenna Top II) was a Maya ruler of Caracol (in present-day Belize). He reigned AD 618âÂÂ658.
Küan was a younger son of the king Yajaw Teü Küinich II, and his mother was Lady Batzü Ekü (possibly Ix Tiwool Chan Ekü Lem) of Yaxha. His half-brother was Knot Ajaw. His paternal grandfather was Küan I.
In the view of the substantial expansion from the site core into the surrounding area during his reign, Küan II might be considered Caracol's most successful ruler. The wealth underlying this expansion was widespread, as indicated by the quality of grave goods and architecture in the outlying districts; Caracol's system of roadways also expanded to accommodate the growing population.
Having taken his grandfather's name upon his accession to rulership, Küan often combined it with his childhood name (Sak Büaah Witzil [or Sak Witzil Büaah]) in order to distinguish his inscriptions from those of his ancestor. He was a successor of his half-brother.
The fact that his mother, Lady Batzü Ekü, was the more junior wife caused Küan II to emphasize his royal legitimacy and his mother's importance in the text of Stela 3.
It is to Küan that we owe Altar 21's account of his father's reign, which saw a shift from the overlordship of Tikal to that of the Kaan ("Snake") kingdom, as well as the great Tikal reversal of AD 562. He records all of his father's major period endings, but he omits that of his half-brother.
Mentions of the Snake kingdom in Küan II's inscriptions include a reference to Sky Witness (possibly his death) in 572; an event performed under the auspices of Yuknoom Chan in 619; the accession of Tajoom Uküab Küahkü in 622; the receipt of a gift from Tajoom Uküabü Küahkü in 627; the latter's death in 630; and two successful war events involving Yuknoom Head in 631 and 636. It was probably toward the end of this timespan that the Snake kingdom became established in Calakmul.
One of Küan II's most important monuments is the Naranjo Hieroglyphic Stairway.
He died on July 21, 658.
