Perhaps the generic name given to the king of the Kurūs. The Aṅguttara Nikāya AN.iii.369f. mentions a king Koravya who owned a large banyan tree named Suppatiṭṭha. According to the Raṭṭhapāla Sutta, MN.ii.65 Thag.776.ff. in the Buddha’s day, too, the ruler of Kuru was called Koravyarājā, and he owned a park which seems to have been called Migacīra.
