Oka Crisis
The Mohawk people were in the Montreal area starting from the 1700s. In 1717, some land in the Montreal region was given to the Roman Catholic Church to use as a seminary. Part of this land included a Mohawk burial site. In 1868, Joseph Onasakenrat, a leader of the Mohawk, wrote a letter to the seminary that said that part of the land was meant for the Mohawk people to use. A year later, he and some other Mohawk attacked the seminary but were unable to get the land in the end.
