Chrisitianity

Explanation:

The Americas:

When British colonist began settling in the Americas, they brought with them Chrisitanity and tried to spread this religion to the Native Americans. The main reason why colonist left Great Britian is because, they wanted religious freedom...such as Puritans and Protestants came to the Americas.

Asia:

(I don't remember too much why it spread there but I'll try my best) Missionary works for Chrisitanity began to spread in Asia( especailly Japan), and there was the influence of trade/merchants bringing their culture to Japan.
