Who of the following founded a new city on the south bank of a tributary to river Krishna and undertook to rule his new kingdom as the agent of a deity to whom all the land south of the river Krishna was supposed to belong?

Harihara I, along with his brother Bukka I, founded the Vijayanagara Empire on the south bank of the Tungabhadra (a tributary of the Krishna) and ruled as the "agent" or regent of the deity Virupaksha. While Prataparudra II of the Kakatiya dynasty is a tempting choice due to the shared geographical context of the Deccan, he did not establish a new capital under this specific divine mandate. The core concept tested is the socio-religious legitimacy and political foundation of the Vijayanagara Empire as a bulwark against northern invasions.
