Inscriptions later summarized on Altar Q record the founder K’inich Yax K’uk’ Mo’ taking royal authority in 426 and arriving to assume rule at Copán in early 427, establishing the dynasty that would govern for centuries.
K’inich Yax K’uk’ Mo’ is attested in later texts as Copán’s first dynastic ruler, with reign traditionally placed in the late 420s–430s CE, anchoring subsequent royal legitimacy claims.
Chan Imix K’awiil (“Smoke Jaguar”) came to power in 628 CE and ruled for decades, a span associated with Copán’s growth and later monumental programs that referenced earlier kings.
Uaxaclajuun Ub’aah K’awiil (“18-Rabbit”) took the throne in 695 CE and is widely linked to Copán’s Late Classic artistic and architectural florescence, including major plaza and monument programs.
Stela A was dedicated in 731 CE as part of 18-Rabbit’s extensive sculptural cycle that helped define Copán’s reputation for high-quality Classic Maya stone carving.
Texts indicate that Quiriguá’s ruler K’ak’ Tiliw Chan Yopaat adopted the title k’uhul ajaw in 734, marking a political break that weakened Copán’s control over the Motagua Valley trade corridor.
Copán’s Great Ballcourt (Ballcourt A-III) was dedicated in 738 CE, representing one of the last major building projects associated with 18-Rabbit before his downfall.
In 738 CE, Copán’s ruler Uaxaclajuun Ub’aah K’awiil was captured by Quiriguá and later beheaded, an event commonly treated as a turning point leading to a political and monumental “hiatus” at Copán.
K’ak’ Joplaj Chan K’awiil (“Smoke Monkey”) ruled from 738–749, a period with reduced monument commissioning associated with Copán’s loss of power and resources after Quiriguá’s break.
K’ak’ Yipyaj Chan K’awiil (“Smoke Shell”) ruled from 749–763 and is credited with renewing construction, including rebuilding Structure/Temple 26 and reinstalling and enlarging the Hieroglyphic Stairway.
Research summarized by Harvard’s Peabody Museum notes that additions to an earlier version of Copán’s Hieroglyphic Stairway were dedicated in 756 CE, expanding a key text of dynastic history.
Yax Pasaj Chan Yopaat took power in 763 CE and undertook renovations and commemorative programs that explicitly linked his authority to the founder and earlier rulers.
In 776 CE, Altar Q was dedicated under Yax Pasaj Chan Yopaat, depicting and naming sixteen Copán rulers from the founder onward and serving as a major political statement of legitimate succession.
Ukit Took acceded in 822 CE and is widely treated as Copán’s last dynastic ruler; his unfinished commemorative monument (Altar L) reflects the polity’s rapid terminal decline.
UNESCO summarizes that Copán’s major developmental phases ended with abandonment in the early 10th century, following the ninth-century political and demographic contraction after the dynasty’s last rulers.
