What did expansionists want to acquire?

Expansionists in the 19th century aimed to acquire new territories to expand the United States, driven by the belief in Manifest Destiny—the idea that Americans were destined to spread across the continent. They sought to obtain land for agriculture, resources, and to provide opportunities for settlers. Key areas of interest included Texas, Oregon, and California, which were seen as vital for the nation's growth and economic development. This desire often led to conflicts with indigenous peoples and other nations.
