Is there any way for the world to end up with a heavily Indianized Arabian Peninsula? Obviously, Indian culture heavily influenced Indochina and Indonesia, so we know that the cultural dominance could happen, but how would it come about? Arabia appears to be about the same distance over water as either of the other two, but I don't know much about currents or monsoon winds, which might make a greater Indian connection with Arabia more difficult. There is also the issue of competition with Persia, which historically had a lot of influence in the Gulf coast. I think it would at least have to be pre-Islam, since Islam was very Arabic in its origin and promoted the Arabic language heavily. Could Hinduism and Buddhism spread there? What other factors could lead India to influence Arabic culture more?
