The Indus Valley Civilization (IVC), also known as the Harappan Civilization, flourished from approximately 2500 BC to 1750 BC and is regarded as the first urban civilization of the Indian subcontinent. It is famous for advanced town planning, a grid road system, standardized burnt bricks, and the world's first known urban drainage system. Rakhigarhi (Haryana) is the largest site overall; Bhirrana (Haryana) is the oldest.
