Context: The Spirit Lake Massacre (March 8–12, 1857) was an attack by a "Wahpekute" band of Santee Sioux on scattered Iowa frontier settlements during a severe winter.  Suffering a shortage of food, the renegade chief Inkpaduta (Scarlet Point) led 14 Sioux against the settlements near Okoboji and Spirit lakes in the northwestern territory of Iowa near the Minnesota border, in revenge of the murder of Inkpaduta's brother, Sidominadotah, and Sidominadotah's family by Henry Lott.  The Sioux killed 35-40 settlers in their scattered holdings, took four young women captive, and headed north.  The youngest captive, Abbie Gardner, was kept a few months before being ransomed in early summer.  It was the last Native American attack on settlers in Iowa, but the events increased tensions between the Sioux and settlers in the Minnesota Territory. Rain-in-the-Face (Lakota: Ité Omáǧažu )(in Standard Lakota Orthography) (c. 1835 – September 15, 1905) was a warchief of the Lakota tribe of Native Americans.  His mother was a Dakota related to the band of famous Chief Inkpaduta.  He was among the Indian leaders who defeated George Armstrong Custer and the U.S. 7th Cavalry Regiment at the 1876 Battle of Little Big Horn. The Spirit Lake Tribe (in Santee Dakota: "Mni Wakan Oyate", formerly known as Devils Lake Sioux) is a federally recognized tribe based on a reservation located in east-central North Dakota on the southern shores of Devils Lake.  It is made up of people of the Pabakse ("Iháŋkthuŋwaŋna"), Sisseton ("Sisíthuŋwaŋ") and Wahpeton ("Waȟpéthuŋwaŋ") bands. The Flandreau Indian Reservation is an Indian reservation, belonging to the federally recognized Flandreau Santee Sioux Tribe of South Dakota.  They are Santee Dakota people, part of the Sioux tribe of Native Americans.  The reservation is located in Flandreau Township in central Moody County in eastern South Dakota, near the city of Flandreau. The Lake Traverse Indian Reservation is the homeland of the Sisseton Wahpeton Oyate, a branch of the Santee Dakota group of Native Americans.  The reservation is located in parts of five counties in extreme northeastern South Dakota and parts of two counties in southeastern North Dakota, United States.  Over 60 percent of its land area lies in Roberts County, South Dakota, but there are lesser amounts in Marshall, Day, Grant, and Codington counties in South Dakota, as well as Sargent and Richland counties in North Dakota.  Its resident population of 10,408 persons was counted during the 2000 census.  About one-third of its inhabitants claim to be of solely Native American heritage.  Its largest community is the city of Sisseton, South Dakota. Ishtakhaba (Dakota: Ištáȟba), a.k.a. Chief Sleepy Eye, was a Native American chief of the Sisseton Dakota tribe.  He became chief sometime between 1822 and 1825, receiving a commission from the Bureau of Indian Affairs as chief in 1824, and remained chief until his death in 1860.  His band, known as the Swan Lake or Little Rock Band, hunted "in southwestern Minnesota and southeastern Dakota ... between Swan Lake and Coteau des Prairies," until forced to move to reservation land near the Minnesota River in the wake of the 1857 Spirit Lake Massacre. The Oglala Lakota or Oglala Sioux (pronounced ] , meaning "to scatter one's own" in Lakota language) are one of the seven subtribes of the Lakota people who, along with the Dakota, make up the Great Sioux Nation.  A majority of the Oglala live on the Pine Ridge Indian Reservation in South Dakota, the eighth-largest Native American reservation in the United States.  The Oglala are a federally recognized tribe whose official title is the Oglala Sioux Tribe (previously called the Oglala Sioux Tribe of the Pine Ridge Reservation, South Dakota).  Of note, however, some Oglala reject the term "Sioux" because it was a name give to them by the Chippewa Nation, who were historically enemies of the Lakota.  The term means "snake" and, as such, is seen as a slur. South Dakota ( ; [ˌsɑʊθ dəˈko̞ɾə] ) is a state in the Midwestern region of the United States.  It is named after the Lakota and Dakota Sioux Native American tribes, who compose a large portion of the population and historically dominated the territory.  South Dakota is the 17th most expansive, but the 5th least populous and the 5th least densely populated of the 50 United States.  Once the southern part of the Dakota Territory, South Dakota became a state on November 2, 1889, simultaneously with North Dakota.  Pierre is the state capital and Sioux Falls, with a population of about 171,000, is South Dakota's largest city. Inkpaduta (Dakota: Iŋkpáduta, variously translated as "Red End," "Red Cap," or "Scarlet Point") (about 1797–1881) was a war chief of the Wahpekute band of the Dakota (Eastern or Santee Dakota) during the 1857 Spirit Lake Massacre and later Western Sioux actions against the United States Army in the Dakota Territory, Wyoming and Montana. The Spirit Lake Massacre Log Cabin, also known as the Gardner Log Cabin, is located in Arnolds Park, Iowa, United States.  Rowland Gardner had led a group of settlers into the region in 1856, and he built this cabin in July of that year.  On March 8, 1857, a band of renegade Wahpekuta Sioux who had been alienated from the tribal structure attacked the Gardner family and other settlers in the immediate areain an incident known as the Spirit Lake Massacre.  Led by Inkpaduta, the band of outlaws raided both Indians and white settlers for a period of about 30 years.
