What happened
Suryavarman II took the Khmer throne in 1113 by assassinating his great-uncle, the reigning king Dharanindravarman I. World History Encyclopedia notes he is said to have compared the coup to destroying a serpent, though what exactly that reference meant, and what motivated the killing, is not recorded and remains unclear. Rather than rely on descent alone to justify his rule, Suryavarman II built legitimacy through accomplishment: he opened formal relations with Song dynasty China, which boosted trade and strengthened the Khmer economy, even though his military campaigns against Dai Viet and the Cham kingdoms mostly failed. He is remembered as one of the strongest kings of the empire despite, or partly because of, how he came to power.
Why it matters
Suryavarman II's need to prove his legitimacy after a violent succession is the immediate context for the temple he built next. A usurper with an uncertain claim to the throne had every reason to construct the largest religious monument the region had ever seen.
How we know
The succession and the assassination of Dharanindravarman I are recorded across multiple Khmer inscriptions from Suryavarman II's reign, though the inscriptions describe the act allusively rather than in narrative detail, which is why the king's exact motive remains unknown to historians.
