7th Cavalry Regiment in the context of "Population history of the Indigenous peoples of the Americas"

Black Kettle (Cheyenne: Mo'ohtavetoo'o) (c. 1803 – November 27, 1868) was a leader of the Southern Cheyenne during the American Indian Wars. Born to the Northern Só'taeo'o / Só'taétaneo'o band of the Northern Cheyenne in the Black Hills of present-day South Dakota, he later married into the Wotápio / Wutapai band (one mixed Cheyenne-Kiowa band with Lakota Sioux origin) of the Southern Cheyenne.

Black Kettle is often remembered as a peacemaker who accepted treaties with the U.S. government to protect his people. On November 27, 1868, while attempting to escape the Battle of Washita River with his wife, he was shot and killed by soldiers of the U.S. 7th Cavalry.

"Garryowen" is an Irish tune for a jig dance. It has become well known as a marching tune in Commonwealth and American military units, most famously George Armstrong Custer's 7th Cavalry Regiment.

The Battle of the Little Bighorn, known to the Lakota and other Plains Indians as the Battle of the Greasy Grass, and commonly referred to as Custer's Last Stand, was an armed engagement between combined forces of the Lakota Sioux, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army. It took place on June 25–26, 1876, along the Little Bighorn River in the Crow Indian Reservation in southeastern Montana Territory. The battle, which resulted in the defeat of U.S. forces, was the most significant action of the Great Sioux War of 1876.

Most battles in the Great Sioux War, including the Battle of the Little Bighorn, were on lands those natives had taken from other tribes since 1851. The Lakotas were there without consent from the local Crow tribe, which had a treaty claim on the area. Already in 1873, Crow chief Blackfoot had called for U.S. military actions against the native intruders. The steady Lakota incursions into treaty areas belonging to the smaller tribes were a direct result of their displacement by the United States in and around Fort Laramie, as well as in reaction to white encroachment into the Black Hills, which the Lakota consider sacred. This pre-existing Indian conflict provided a useful wedge for colonization and ensured the United States a firm Indian alliance with the Arikaras and the Crows during the Lakota Wars.

The No Gun Ri massacre (Korean: 노근리 양민 학살 사건) was a mass killing of South Korean refugees by U.S. military air and ground fire near the village of Nogeun-ri (노근리) in central South Korea between July 26 and 29, 1950, early in the Korean War. In 2005, a South Korean government inquest certified the names of 163 dead or missing and 55 wounded, and added that many other victims' names were not reported. The No Gun Ri Peace Foundation estimates 250–300 were killed, mostly women and children.

The incident was little-known outside Korea until publication of an Associated Press (AP) story in 1999 in which veterans of the U.S. Army unit involved, the 7th Cavalry Regiment, corroborated survivors' accounts. The AP also uncovered declassified U.S. Army orders to fire on approaching civilians because of reports of North Korean infiltration of refugee groups. In 2001, the United States Army conducted an investigation and, after previously rejecting survivors' claims, acknowledged the killings, but described the three-day event as "an unfortunate tragedy inherent to war and not a deliberate killing". Then-President Bill Clinton issued a statement of regret, adding the next day that "things happened which were wrong", but survivors' demands for an apology and compensation were rejected.

The Henry repeating rifle is a lever-action tubular magazine rifle. It is famous for having been used at the Battle of the Little Bighorn and having been the basis for the iconic Winchester rifle of the American Wild West.

Designed and introduced by Benjamin Tyler Henry in 1860, the original Henry was a sixteen-shot .44 caliber rimfire breech-loading lever-action rifle. It was produced from 1860 until 1866 in the United States by the New Haven Arms Company. The Henry was adopted in small quantities by the Union in the American Civil War, favored for its greater firepower than the standard-issue carbine. Many later found their way West, notably in the hands of a few of the Sioux and Cheyenne in their defeat of George Armstrong Custer's U.S. Cavalry troops in June 1876.

The Ghost Dance War was the military reaction of the United States government against the spread of the Ghost Dance movement on Lakota Sioux reservations in 1890 and 1891. The United States Army designation for this conflict was Pine Ridge Campaign. White settlers called it the Messiah War. Lakota Sioux reservations were occupied by the US Army, causing fear, confusion, and resistance among the Lakota. It resulted in the Wounded Knee Massacre wherein the 7th Cavalry killed over 250 Lakota, primarily unarmed women, children, and elders, at Wounded Knee on December 29, 1890; as a recognition for surviving an ambush, the US government awarded the Medal of Honor to 20 US soldiers. The end of the Ghost Dance War is usually dated January 15, 1891, when Lakota Ghost-Dancing leader Kicking Bear decided to meet with US officials. However, the US government continued to use the threat of violence to suppress the Ghost Dance at the Pine Ridge, Rosebud, Cheyenne River, and Standing Rock reservations.
