Mauryan Empire was spread over a large part of the Indian sub-continent and also included Kandahar in modern Afghanistan. In around 187 BC, the Mauryan Empire met its end.
The disintegration of the Mauryan empire led to the rise of many regional kingdoms in different parts of the country. At the same time, we witness invasions by various groups of people based in Central Asia and western China. These were Indo-Greeks, the Scythians or the Shakas, the Parthians or the Pahlavas and the Kushanas.
It was through such political processes that India came in closer contact with the central Asian politics and culture.
