While the Sassanids always adhered to a stated policy of religious proselytization, and sporadically engaged in persecution or forced conversion of minority religions, the Kushans preferred to adopt a policy of religious tolerance.
Mentres os sasánidas sempre tiveron un concepto relixioso ligado á política proselitista estatal, e esporadicamente perseguían ou forzaban a conversión das minorías relixiosas, os kushan eran máis partidarios da tolerancia relixiosa.
