What was the primary purpose of Spain's colony of New Mexico?

The primary purpose of Spain's colony of New Mexico was to establish a foothold in North America for religious, economic, and strategic reasons. The Spanish aimed to convert Indigenous peoples to Christianity, primarily through the efforts of missionaries, while also seeking to exploit the region’s resources and expand their territorial claims. Additionally, New Mexico served as a buffer against rival European powers and as a base for further exploration and colonization in the region.
