Why do Walter Raleigh want discourse of western planting written?

Walter Raleigh wanted "A Discourse of Western Planting" written to advocate for the colonization of the Americas, emphasizing the economic and strategic benefits for England. He believed that establishing colonies would enhance national wealth, provide new resources, and strengthen England's position against rival powers like Spain. Additionally, Raleigh aimed to promote the idea of spreading Christianity and civilization to indigenous peoples. Ultimately, the discourse served as both a persuasive argument for investors and a roadmap for potential settlers.
