Ancient cities and enduring texts
The history of the Indian subcontinent reaches back thousands of years. The urban settlements of the Indus Valley civilisation flourished from roughly 2600 BCE, with carefully planned cities such as Harappa and Mohenjo-daro.
Later Vedic traditions developed across northern India. The Rigveda, composed over a long period in the second millennium BCE, is among the earliest surviving literary sources for this era. As settlements expanded eastward towards the Ganges, new kingdoms, trade networks and centres of learning emerged.
