What happened

What happened

On February 22, 1855, in Washington, Commissioner George W. Manypenny and chiefs of the Mississippi, Pillager and Lake Winnibigoshish bands of Chippewa signed a treaty. The bands ceded "all their right, title, and interest in, and to, the lands now owned and claimed by them" in Minnesota Territory within a described boundary. Article 2 reserved separate tracts for permanent homes, including townships around Mille Lacs and tracts on the Mississippi. The United States agreed to pay the Mississippi bands $10,000 in goods and $50,000 to settle their present engagements, plus annuities.

Treaties Matter says that with the collapse of the fur trade, the Ojibwe depended more on annuities, and that the U.S. intended them to become farmers on individually owned plots, promising to plow 675 acres for the whole population.

In Minnesota v. Mille Lacs Band (1999) the Supreme Court held that the Chippewa retained the hunting and fishing rights from the 1837 treaty because the 1855 treaty was "devoid of any language expressly mentioning usufructuary rights." Treaties Matter adds that the 1855 reservation tracts were later enlarged, ceded and restored by treaties and acts of Congress.

The law behind it

The legal ideas behind the decisions, and related records without a date. Court cases and laws with a date are in what happened next, above.

  • Legal doctrine

    criminal jurisdiction

    Who may prosecute a crime in Indian country depends on who the offender and victim are and where it happened.

  • Legal doctrine

    diminishment

    Only Congress can shrink a reservation, and courts require a clear statement; Solem, Hagen and Parker show how that test works.

  • Legal doctrine

    disestablishment

    Disestablishment means Congress ended a reservation entirely; courts require clear intent from Congress, and McGirt (2020) held the Creek Reservation was never disestablished.

  • Legal doctrine

    indian country

    Federal law defines 'Indian country' as reservations, dependent Indian communities and Indian allotments; the definition decides which government's laws apply.
