(*This was a treaty made between the Anishinaabe and Haudenosaunee after the French and Indian War. Newcomers were then incorporated into it over the years, notably in 1764 with The Royal Proclamation/The Treaty of Niagara.)
The purpose of the acknowledgement started in British Columbia, where there are no treaties at all. So people are actually living, working and meeting on stolen land. Its popularity has spread as an acknowledgment of Indigenous presence and assertion of sovereignty. People use it in different ways, such as at opening events and meetings.
