Lieutenant Colonel George Armstrong Custer was a U.S. Army cavalry commander whose force was wiped out by Lakota, Cheyenne, and Arapaho warriors at the Battle of Little Bighorn (1876), a Native victory that triggered an intensified U.S. military campaign against Plains Indians during westward expansion.
George Armstrong Custer was a flashy Civil War cavalry officer who became one of the most famous (and infamous) commanders of the Indian Wars on the Great Plains. In June 1876, he led the 7th Cavalry against a massive encampment of Lakota Sioux, Cheyenne, and Arapaho along the Little Bighorn River in Montana Territory. Badly underestimating the size of the force led by leaders like Sitting Bull and Crazy Horse, Custer split his troops and attacked. He and over 200 of his men were killed in what newspapers dramatized as "Custer's Last Stand."
For APUSH, Custer matters less as an individual and more as evidence of a pattern. The campaign he died in started because the U.S. government violated the Treaty of Fort Laramie after gold was discovered in the Black Hills, land guaranteed to the Sioux. His defeat was the most famous Native military victory of the era, but it backfired strategically. Public outrage gave the government cover to flood the Plains with troops, crush armed resistance, and force tribes onto reservations. Custer's story is the violent-conflict piece of KC-6.2.II.C and the treaty-violation piece of KC-6.2.II.D rolled into one episode.
Custer lives in Unit 6, Topic 6.3 (Westward Expansion: Social and Cultural Development) and supports learning objective APUSH 6.3.A, explaining the causes and effects of western settlement from 1877 to 1898. The CED's essential knowledge says competition for land and resources among white settlers, American Indians, and Mexican Americans led to rising violent conflict (KC-6.2.II.C), and that the U.S. government violated treaties and answered resistance with military force (KC-6.2.II.D). Little Bighorn is the go-to example for both. It also feeds the Migration and Settlement (MIG) and America in the World themes, because the fight was ultimately about who would control western land as railroads, miners, and ranchers pushed in. When you need concrete evidence that Native resistance was real and that federal policy escalated to outright military conquest, Custer's defeat is your specific.

Battle of Little Bighorn (Unit 6)
This is the event Custer is famous for. Remember the cause-and-effect chain in both directions. Gold in the Black Hills led to a treaty violation, which led to Sioux resistance, which led to Custer's defeat, which led to a harsher U.S. military crackdown.
Indian Wars (Unit 6)
Custer's campaign was one chapter in decades of armed conflict on the Plains. Little Bighorn was a Native win inside a war Native nations ultimately lost, as the army's response after 1876 broke organized armed resistance.
Dawes Act (Unit 6)
Once military resistance was crushed in the years after Custer's defeat, federal policy shifted from fighting tribes to dissolving them. The Dawes Act of 1887 broke up tribal lands into individual allotments, swapping bullets for assimilation as the tool of conquest.
Manifest Destiny (Units 5-6)
The ideology that justified the whole collision. The belief that white Americans were destined to fill the continent is why settlers, railroads, and the army kept pushing into treaty-guaranteed land in the first place. Custer's campaign is Manifest Destiny enforced at gunpoint.
Custer rarely appears by name as the answer itself. Instead, expect Little Bighorn or the broader Indian Wars to show up in multiple-choice stimulus sets, often paired with an excerpt about the Black Hills, the Treaty of Fort Laramie, or Plains resistance, with questions asking about causes (competition for land, treaty violations) or effects (military force, reservation policy). No released FRQ has used Custer's name verbatim, but he is exactly the kind of specific evidence that earns points on a long essay or short-answer question about westward expansion's effects on American Indians. The move that scores is connecting the event to the pattern. Don't just narrate the battle. Use it to show that the federal government broke treaties and used military force when Native nations resisted (KC-6.2.II.D).
Both are landmark violent episodes of the Plains conflicts, but they sit at opposite ends of the story. Little Bighorn (1876) was a Native military victory where Custer's 7th Cavalry was destroyed by Lakota, Cheyenne, and Arapaho fighters. Wounded Knee (1890) was a massacre of mostly unarmed Lakota by the U.S. Army (also the 7th Cavalry) during the Ghost Dance movement, and it marks the end of armed Plains resistance. If a question asks about a Native victory, that's Little Bighorn. If it asks about the closing of the Indian Wars, that's Wounded Knee.
Custer was the U.S. cavalry commander killed with over 200 of his men at the Battle of Little Bighorn in 1876, the most famous Native American military victory of the Indian Wars.
The campaign happened because the U.S. government violated the Treaty of Fort Laramie after gold was discovered in the Black Hills, land guaranteed to the Sioux.
Custer's defeat backfired for Native nations because public outrage justified a much larger military campaign that forced Plains tribes onto reservations.
On the exam, use Custer and Little Bighorn as specific evidence for KC-6.2.II.C (violent conflict over western land and resources) and KC-6.2.II.D (treaty violations met with military force).
Don't confuse Little Bighorn (1876, Native victory) with Wounded Knee (1890, U.S. massacre of Lakota that ended armed Plains resistance).
Custer was a U.S. Army cavalry commander during the Civil War and the Indian Wars, best known for being defeated and killed by Lakota, Cheyenne, and Arapaho forces at the Battle of Little Bighorn in 1876. In APUSH he's evidence for violent conflict and treaty violations during westward expansion (Topic 6.3).
No. It actually accelerated the U.S. military campaign against Plains Indians. Public outrage over "Custer's Last Stand" gave the government political cover to send more troops, and within a few years most Plains nations had been forced onto reservations.
Little Bighorn (1876) was a Native victory in which Custer's 7th Cavalry was destroyed. Wounded Knee (1890) was a U.S. Army massacre of mostly unarmed Lakota during the Ghost Dance movement, and it marks the end of armed resistance on the Plains.
After gold was found in the Black Hills, the U.S. violated its treaty with the Sioux and ordered them onto reservations. Custer's column was part of the army campaign against bands led by Sitting Bull and Crazy Horse, and he attacked a far larger encampment than he expected.
He can appear as stimulus material or as the specific evidence behind a question about the Indian Wars. You're not required to know his biography, but you should be able to use Little Bighorn as an example of Native resistance and the federal government's military response under learning objective APUSH 6.3.A.
