Which tribe eventually allied with the wichita to promote trade

Comanche

Explanation:

Some Wichita groups moved to Oklahoma and Texas, and they had extensive contact with Plains Indians during the 1700s. This led them to adopt many of their traits, such as raiding and trading. They also established close alliances with the French and the Comanche. The Wichita and Comanche people were collectively known as Norteños. This alliance began to break up in the 1770s, as the Wichita began to imrpove relationships with the Spanish.
