Devaraya I, who ruled the Vijayanagara Empire during the early 15th century, is credited with significant infrastructural advancements, including the construction of a large dam across the Tungabhadra River and an extensive canal system. This was crucial for irrigation, supporting agriculture and enhancing the economy of the empire, indicative of the rulers’ focus on administrative efficiency and resource management. Such infrastructure projects not only demonstrate the technological capabilities of the era but also align with the broader themes of governance and agrarian development highlighted in UPSC syllabus materials like NCERT textbooks on medieval Indian history.
