were able to advance through cultural exchange

Explanation:

The three biggest religions by followers, the Christianity, Islam, and Buddhism all started at some place and then started to spread around on much larger area. All three religions managed to advance through cultural exchange, and managing to get lot of followers in the process. It has to be noted though that the Buddhism was actually the only of the three that spread around in a totally peaceful manner. The Christianity and Islam did spread through cultural exchange, but very often they also forced the people to convert to their religion. The Christianity has abandoned that method, while the Islam is the only of the three that still practices such measures in the present.
