Karikala Chola and the Early Cholas

Karikala Chola is the most prominent king of the early (Sangam-era) Chola line, celebrated in poems such as the Pattinappalai for his military victories and his contributions to agrarian infrastructure. He is traditionally credited with constructing or strengthening the Kallanai (Grand Anicut) across the Kaveri river, an engineering feat that regulated water for irrigation across the Kaveri delta and is still functional today after periodic renovations — making it one of the oldest water-management structures in continuous use anywhere in the world. Under his rule, the port city of Puhar (Kaveripattinam) is described as a flourishing hub of international trade. His reign represents the zenith of the early Chola polity before a long gap in the historical record until the imperial Cholas re-emerge under Vijayalaya in the 9th century.
