A Solar-Dynasty Ancestry, Kept Separate
Buddhist tradition, recorded in the Mahavamsa and later commentarial literature, traces the Shakya clan's ancestry back to the solar-dynasty king Okkaka (identified with the Puranic and epic Ikshvaku), paralleling the lineage claimed by the Ramayana's Ikshvaku dynasty. This is the Buddhist textual tradition's own genealogical claim, recorded here separately from — not merged with — the Ramayana project's Ikshvaku line, since the two traditions are not treated as a single continuous historical record.
This article follows the Pali Canon and its commentarial tradition as the primary early Buddhist textual source; where sources genuinely disagree on a detail (such as an exact parentage), that disagreement is noted rather than resolved into a single invented certainty.
