Amy is writing a paper on the spread of culture through trade. her teacher asks her to look at how islam was spread through trade in asia. during her research, amy comes up with the argument that trade was better than conquest or warfare at spreading religions such as islam. more than one choice! mahmūd attacked india because of its wealth from the silk road trade. islamic scholars moved from baghdad to delhi in 1258.the  ramayana  and  mahabharata  are popular subjects of southeast asian art. conquering armies did not spread religion and culture efficiently. islam reached southern india before mahmūd attacked northern india.
