The Ikshvaku (IAST: Ikṣvāku) dynasty ruled in the eastern Krishna River valley of India, from their capital at Vijayapuri (modern Nagarjunakonda in Andhra Pradesh) during approximately 3rd and 4th centuries CE. The Ikshvakus are also known as the Andhra Ikshvakus or Ikshvakus of Vijayapuri to distinguish them from their legendary namesakes. The Ikshvaku kings were Shaivites and performed Vedic rites, but Buddhism also flourished during their reign. Several Ikshvaku queens and princes contributed to the construction of the Buddhist monuments at present-day Nagarjunakonda.
