Son of the 695 victor; builder of Temple IV — tallest pre-Columbian structure in the Americas (70 m).
Yikʼin inherited Tikal at its restored peak and pushed it higher. His 743–744 campaigns broke El Peru-Waka, Calakmulʼs key ally, and captured its king. Stela 11 shows him with bound captives; Temple IVʼs lintels show his queen. At 70 m Temple IV looked clean over the canopy to rival cities (WHE, Tikal).
Dedicated 741. Nine terraces, giant roof-comb with maize god mosaic. From its top a king saw 30 km of forest — and every enemy saw Tikal. Tallest ancient American building until modern times.
Two campaigns smashed Waka, seized its king and the Maize God effigy. Tikal controlled the San Pedro river trade. Calakmul, already beaten in 695, lost its western shield forever.
