1887, the government sought to individualize tribal lands by authorizing allotments held in individual tenure. Generally, the allocation process led to grouping family holdings and, in some cases, this sustained pre-reservation clan or other patterns. There had been a few allotment programs ahead of the Dawes Act. However, the vast fragmentation of reservations occurred from the enactment of this act up to 1934, when the Indian Reorganization Act was passed. However, Congress authorized some allotment programs in the ensuing years, such as on the Palm Springs/Agua Caliente Indian Reservation in California. Allotment set in motion a number of circumstances: individuals could sell (alienate) the allotment – under the Dawes Act, it was not to happen until after twenty-five years. individual allottees who would die intestate would encumber the land under prevailing state devisement laws, leading to complex patterns of heirship. Congress has attempted to mollify the impact of heirship by granting tribes the capacity to acquire fragmented allotments owing to heirship by financial grants. Tribes may also include such parcels in long-range land use planning. With alienation to non-Indians, their increased presence on numerous reservations has changed the demography of Indian Country. One of many implications of this fact is that tribes can not always effectively embrace the total management of a reservation, for non-Indian owners and users of allotted lands contend that tribes have no authority over lands that fall within the tax and law-and-order jurisdiction of local government. The demographic factor, coupled with landownership data, led, for example, to litigation between the Devils Lake Sioux and the State of North Dakota, where non-Indians owned more acreage than tribal members even though more Native Americans resided on the reservation than non-Indians. The court decision turned, in part, on the perception of Indian character, contending that the tribe did not have jurisdiction over the alienated allotments. In a number of instances—e.g., the Yakama Indian Reservation—tribes have identified open and closed areas within reservations. One finds the majority of non-Indian landownership and residence in the open areas and, contrariwise, closed areas represent exclusive tribal residence and related conditions. Indian Country today consists of tripartite government—i. e., federal, state and/or local, and tribal. Where state and local governments may exert some, but limited, law-and-order authority, tribal sovereignty is diminished. This situation prevails in connection with Indian gaming because federal legislation makes the state a party to any contractual or statutory agreement. Finally,
