Raghuvaṃśa dynasty

Raghuwamsa or Raghu race is a legendary lineage of warrior kings tracing its ancestry to the Hindu solar deity Surya. Kalidasa's famous work, Raghuvaṃśa depicts the legend of this race. The progenitor of the lineage was Raghu, son of the emperor Dileepa. Raghu was father of Aja, and thus grandfather of Dasaratha, and great-grandfather of Rama. They are thus of the Raghuvamsa ("dynasty of Raghu") lineage.
