Answer:
Hello. You have not provided the necessary source to answer this question, which makes it impossible to answer. However, I can help you by stating that the purpose of Chief Ackowanothie's speech was to encourage peace between Europeans and his tribe.
Step-by-step explanation:
As we read Chief Ackowanothie's speech, we can see that his main objective is to promote peace because of the protection of his tribe. Chief Ackowanothie says that his tribe does not want to create conflicts with European explorers and also does not have the objective of expelling them. All that Chief Ackowanothie wants is to guarantee the protection of his people, within their own lands, which should not be invaded and plundered, nor exploited.
