Kulottunga Chola I

Kulottunga Chola I, born as Rajendra Chalukya, ascended the Chola throne after his maternal uncle's death. He was the son of a Chalukya prince and a Chola princess, merging the two royal lines and ending the conflict between the dynasties.

Kulottunga I led a military campaign into Kalinga (present-day Odisha), defeating the local rulers and incorporating the region into the Chola Empire. This expanded Chola influence along the eastern coast of India.

Kulottunga I sent an embassy to the court of the Song Emperor Shenzong in China. The mission included gifts and trade proposals, strengthening maritime trade links between the Chola Empire and East Asia.

Kulottunga I reorganized the Chola bureaucracy, introducing new revenue assessments and land surveys. He also standardized weights and measures across the empire, improving tax collection and economic efficiency.

Kulottunga I's forces failed to hold the Vengi region (coastal Andhra) against the Western Chalukya king Vikramaditya VI. This loss reduced Chola territory and marked a setback in his later reign.
