Which historical agreement recognized the rights of First Nations in Canada?

The Treaty of Niagara, signed in 1764, is significant as it acknowledged and recognized the rights of First Nations in Canada. This agreement was established in the aftermath of the Seven Years' War and served to affirm the relationship between the British Crown and Indigenous peoples. It aimed to create a peace treaty that not only detailed the rights and land claims of First Nations but also established a framework for future relationships based on mutual respect and understanding.

This treaty is notable for its role in recognizing Indigenous land rights at a time when many agreements were more focused on the interests of colonial powers. It is often considered a milestone in the history of Indigenous-Crown relations in Canada. The other agreements listed either do not specifically address First Nations' rights or focus more on the political landscape rather than Indigenous rights or land claims.
