Answer: B. Spain signed treaties to maintain good relations with American Indians.
Explanation:
The Spanish took over the Louisiana Territory from France around the time the French and Indian War was coming to a close and they found a diverse mix of Native Americans, French people and people of African descent.
The Spanish freed enslaved Native Americans and proceeded to sign treaties with the Native Americans such as the Chickasaw, the Choctaw, and the Tallapoosa and Alabama as they hoped to gain their support in case the Americans ever tried to take Louisiana.
