Answer:
None of the following are the reasons as to why the five tribes of Native Americans supported and fought alongside the confederate army during the American Civil war.
Step-by-step explanation:
Most natives viewed the confederates as the better option because the confederates opposed the idea of the central and federal government system.
They thought this government system lacked respect for the Native American sovereignty. Furthermore, native tribes like the Choctaw and the Creek used to hold slaves and they found an economic and political similarity with the Confederates.
Thus most of the Native American tribes forced up with the confederacy.
