Question

They had no foreign relations

Answer 1

Hey buddy

Here we go

Pre colonial time means that time before any colonial rules


That time our ancestors had no relation with foreigners...

They used to live according to Vedic rules and regulations
The two main religious and cultural communities in the subcontinent: Hindus and Muslims, have remained as separate communities, with little or no integration. Both have rich and proud traditions, both have added to the cultural legacy of India, both have historical claims to ruling the subcontinent. Ancient rivalries and grievances have deepened over the years, periodically erupting into fresh violence. We will look at some of the consequences of this inter-communal strife in late lectures. The Sikh religion was inspired by the desire to overcome this communal division, but in the end simply added a new dimension to the complex mix of cultures in India and neighbouring countries.
