The Treaty of Detroit of 1855 was a treaty between the United States Government and the Ottawa and Chippewa Nations of Indians of Michigan. The treaty contained provisions to allot individual tracts of land to Native people consisting of 40-acre (16 ha) plots for single individuals and 80-acre (32 ha) plots for families, outlined specific tracts which were assigned to the various bands and provided for the severance of the government consolidation of the Ottawa and Chippewa.
