United States Indian Police

The United States Indian Police (USIP) were organized in 1880 by the Union Agency in Muskogee, Indian Territory, to police the Five Civilized Tribes. The USIP recruited many of their police officers from the ranks of the existing Indian Lighthorsemen. Unlike the Lighthorse who were under the direction of the individual tribe, the USIP was under the direction of the Indian Agent assigned to the Union Agency. Many of the US Indian police officers were given Deputy US Marshal commissions that allowed them to cross juridictional boundaries and also to arrest non-Indians.

In 1886 two Indians killed Sam Sixkiller who was the popular Captain of the US Indian Police and a Deputy US Marshal commissioned by the Judicial District of Western Arkansas. After the killers escaped indictment by the tribes, Congress passed a law (24 Stat., 463.) giving the district Federal courts jurisdiction over any Indian who committed a crime against a federally appointed Indian police officer or United States deputy marshal.

Other Indian police

There were basically two other types of police officers on the reservations:
*Indian tribal police.
*:Several Indian tribes replaced hereditary chiefs with constitutional governments. These tribes hired police officers under a number of different titles—sheriffs, constables, regulators, lighthorsemen, etc.—to enforce tribal laws.
*Indian agency police.
*:Many tribes had no recognizable governments and therefore no tribal laws. On these reservations, the Indian agent assigned to the tribe hired Indian police from among tribal members to effect law and order according to Federal, agency, and treaty rules. These were considered federally appointed police officers. The Indian police that killed Sitting Bull were of this kind.
