Final answer:
The Native Americans who lived in West Florida were primarily the Creek. This group, along with the Seminole, utilized the region as a stronghold, which presented challenges to American settlers and the Spanish government due to raids and political control issues.
Step-by-step explanation:
The Native Americans that lived in West Florida were primarily the Creek and later on also included the Seminole as a result of migration and intermarrying. The region of West Florida previously posed difficulties for American settlers due to raids by these nations from the relative safety of the Florida wilderness. Spanish Florida was sparsely populated by colonists and difficult for the Spanish government to control, offering a refuge for these Native American groups, including the Creek, who conducted militant actions against neighboring areas. The Southeast culture, including the Creek, was agriculturally focused and known for constructing mounds for their villages, burial sites, religious sites, and storage facilities.
