The correct answer to this open question is the following.
One way that trade in the Indian Ocean in the period 1200–1450 led to political change was the many contacts that created that trade created in the different Silk Roads and maritime routes of the time. Political and economic changes resulted in the exchange of goods, but also the cultural exchange that resulted from those trade routes. Trade resulted in the growth and expansion of many cities along the Silk Road. Money economies that included a first somewhat kind of credit impulsed the development of the region. Products from China, Persia, India, Africa, and the Middle East created more value in Europe, increasing the interest of more products from these places.
