Quick Summary

King Vasabha, who reigned from 66 to 110 CE, was a significant ruler in Sri Lanka's history. He founded the Lambakanna dynasty and is particularly noted for his contributions to the island's hydraulic civilization. During his reign, large-scale irrigation systems were developed, including the blocking of perennial rivers to create massive reservoirs and the construction of canals to distribute water to fields and cities. This advanced water management significantly boosted agricultural productivity and strengthened royal authority. Vasabha's reign marked a period of technological progress in irrigation, laying the groundwork for future rulers like Mahasena.12
