Kampili was a tiny kingdom on the banks of the Tungabhadra river in present day Karnataka state during the 13th century.
The founder of the kingdom was a Hoysala commander, Singeya Nayaka-III (1280 - 1300) who declared himself independent and created a small chiefdom. He was succeeded by his son Kampilideva in 1300 who faced the wrath of the Hoysala Empire and the Seuna Yadavas of Devagiri but finally fell to the invasion from the north by the forces of Muhammad bin Tughluq, the Sultan of Delhi.
The Vijayanagara Empire that soon came to power (1336) from this territory grew into one of the great empires of India and ruled Southern India for over 200 years.
