Final answer:
Land developers and investors supported Manifest Destiny to make money through land development and investment and to promote territorial expansion.
Step-by-step explanation:
Land developers and investors supported Manifest Destiny for several reasons. One reason was to make money through land development and investment. They saw opportunity in the newly acquired western territories and believed that investing in land would bring them financial gain. Additionally, they wanted to encourage people to move westward and settle new areas, as this would increase demand for land and drive up its value.
Another motivation for land developers and investors was to expand American territory across the continent. Manifest Destiny was a belief that it was the destiny of the United States to expand its territory from the Atlantic Ocean to the Pacific Ocean. By supporting Manifest Destiny, land developers and investors were promoting the idea of territorial expansion, which aligned with their own interests in acquiring and developing land in the west.
While there may have been some individuals who aimed to spread American culture and improve the lives of those living in the west, the primary motivation for land developers and investors was rooted in economic and territorial expansion.
