The Economy of Western Ganga kingdom (350 – 1000 CE) (Kannada: ಪಶ್ಚಿಮ ಗಂಗ ಸಂಸ್ಥಾನ) refers to the economic structure that existed during the rule of this important ruling dynasty of ancient Karnataka. They are known as Western Gangas to distinguish them from the Eastern Gangas who in later centuries ruled over modern Orissa. The Western Ganga sovereignty lasted from about 350 to 550, initially ruling from Kolar and later moving their capital to Talakad on the banks of the Kaveri River in modern Mysore district. Later, they ruled as an important feudatory of larger empires, the imperial Chalukyas of Badami and the Rashtrakutas of Manyakheta.
In the late 10th century, major political changes were taking place in the Deccan. The Rashtrakutas were replaced by the emerging Western Chalukya Empire north of the Tungabhadra river and the Chola Dynasty saw renewed power south of the Kaveri river. The defeat of the Western Gangas to Cholas around 1000 resulted in the end of the Ganga influence over the region. Though territorially a small kingdom, the Western Ganga contribution to polity, culture and literature of the modern south Karnataka region is considered important. The Western Ganga kings showed benevolent tolerance to all faiths but are most famous for their patronage towards Jainism resulting in the construction of fine monuments in such places as Shravanabelagola and Kambadahalli. The kings of this dynasty encouraged the fine arts due to which literature in Kannada and Sanskrit flourished. 9th century Kannada writings refer to King Durvinita of 6th century as an early writer in Kannada language prose. Many classics were written on various subjects ranging from religion to elephant management. The Gangavadi region consists of the malnad region, the plains (Bayaluseemae) and semi-malnad with lower elevation and rolling hills being the buffer region. The main crops of the malnad were paddy, betel leaves, cardamom and pepper and semi-malnad with its lower altitude produced rice, millets such as ragi and corn, pulses, oilseeds and was the base for cattle farming. The plains to the east are the flat lands fed by Kaveri, Tungabhadra and Vedavati rivers where cultivation of sugarcane, paddy, orchards of coconut, areca nut (adeka totta), betel leaves, plantain and flowers (vara vana) were cultivated. The importance of excavation of new irrigation tanks and repairs to existing ones are reflected in epigraphs of the period which phrase it as Arasaru Kattida Kere (tank built by the king) Elites such as gavundas (landlord), feudatory rulers, officials, mahajans (Brahmins), traders (setti) and even artisans contributed to tank building. Other sources of water were wells, natural ponds and catchments of dams (Katta). Inscriptions attesting to irrigation of previously uncultivated lands seems to indicate an expanding agrarian community.
