Several of the resources on this page have nothing to do directly with religion. They are meant, rather, to help students visualize and understand US imperialism—meaning, the United States’ historical and ongoing competition with other nations for territory and regional or global dominance, and the United States’ governance of its territories’ indigenous inhabitants.

You can even adapt, or alter, the resources as long as (a) you credit the creator(s) named at the bottom or the end of each resource, and (b) you allow others to use and adapt your adaptation as freely as you’re being allowed to use and adapt this material.
This website is a work in progress. I hope to add more maps and fact sheets in the future.
