Christian missionaries made it easier for european imperialists to spread western ideas in conquered territories by

establishing western institutions in foreign countries before they were turned into colonies

Explanation:

The religion (Christianity) turned the right hand for the colonial and imperial ambitions of European powers as seen most clearly in Africa, then America, and Asia, to a lesser extent.

The Catholic and Protestant ideology became an instrument of power over the peoples who had a unique cosmovision and were treated as pagans to be converted and saved through evangelization.

The teachings of the monks, were closely related to legitimating the abuse practices often carried in the Encomienda system.

This was mostly seen in America, where the native people eventually became servants to their land, in the notion they were also being converted into a faith which will provide them salvation.

The first experiences the Europeans had with the colonies in Africa had turned into bloody conflicts and in the conquest for the Americas, the use of religion was most present reflecting until the present into many attitudes that remain. The perception of a higher European culture is a result of contrast it with the original and unique cultures like Mayas and Aztecs that are not seen equally.
