One of the great feudatory families that played a prominent part in the history of Karnataka for a period of three centuries (circa 750 to 1055 A. D.) is that of the Nolamba-Pallavas. This family had important relations with other rulers in South India like the Banas, the Rashtrakutas, the Gangas, the Chalukyas and the Vaidumbas. They started their career under the Western Gangas of Talakad, as governors of the territory called Nolambalige 1,000 which comprised portions of Anantapur (Andhra Pradesh), Chitradurga and Tumkur Districts (Mysore State). Nolambalige 1,000 means the district of Nolambalige consisting of 1000 villages and hamlets. This tract was probably bounded by the east by river Pennar and on the West by the river Hagari. In course of time they acquired more territory until it became a 32,000 district in the beginning of the tenth century. This province of 32,000 covered the districts of Tumkur, Chitradurga and portions of Bellary, Anantapur, Kolar and Bangalore.
