Urban centres in Gupta period

The emergence of self-sufficient local units of production is also indicated by the gradual decay of urban centres in the Gupta period. Archaeology shows that Kushana layers belonging to the first-third centuries AD were very flourishing. On the other hand the Gupta layers belonging to the fourth-sixth centuries AD were in state of decline and in many cases Kushana bricks were used in Gupta structures. In many urban sites habitation disappeared after the 6th century AD.
