To begin with, disease as we have learned has played a critical role in determining the outcomes of historical events in many areas of the world. We know of the early disease gradients in Europe and in the Middle East and of the Indus River valley area in India. By the time of the Roman Empire contact with the Middle East and India through trade and conquest had exposed them to the disease pool of these areas and helped create a common disease pool for the Middle East and in Europe most specifically in areas that were under Roman influence. Through conquest Rome spread the common disease pool and helped overcome the isolation of Europe from the Middle East/ Indus Valley disease pool.

The Buddhist were challenged by the state religion of Confucianism which criticized the new religion as alien and foreign. Buddhism became popular largely through the efforts of missionaries like Fa Xian and Xuan Zang and from the support of some of the ruling elite. The over all main reason I believe for the change by these peoples from their pervious religions they had, were the times in which the people lived.
