The history of people indigenous to the North American continent is often glossed over in education. We are badgered with the legend of Native benevolence to the pilgrims who landed on the East Coast on Thanksgiving.

If indigenous history is covered, students are likely to hear a tragic but vague narrative of massacre, disease, and death, a narrative devoid of the specific political and tribal context that is vital to understanding the colonial and imperial relationship between Native communities and the U.S. This renders indigenous bodies invisible. This also contributes to the concealment of contemporary indigenous rights movements, some of which are happening right now.

It is essential that we acknowledge the physical, economic, and psychological trauma that U.S. colonialism has inflicted on indigenous communities. It is also essential that we acknowledge historic and momentous moments of resistance led by indigenous people. Here are seven moments in indigenous history that we should have been taught in school. (For further reading after this article, check out Roxanne Dunbar-Ortiz’s book An Indigenous Peoples’ History Of The United States, which was a vital resource in the creation of this article.)

1. Divide and conquer: the Dawes Act of 1887

An extremely complicated facet of history, The Dawes Act (otherwise known as the “General Allotment Act” or the “Indian Homestead Act”) intended and succeeded in dividing reservations already established by previously set treaties, though this effort was met with resistance.

Through the Dawes Act, tribally owned land decreased from 138 million acres in 1887 to 48 million acres in 1934. This amount of land lost is comparable to the size of the state of Minnesota.The Dawes Act gave the president of the United States “the right to dissolve any reservation created for Indian use … if it is his opinion that it would be advantageous for agricultural and grazing purposes.” Native families were allocated small plots of land—under the stipulation that they pay a land tax. Any indigenous people allocated land who relinquished tribal life were “gifted” with United States citizenship. “Surplus” land left after allocation was sold by the United States to settlers.

This act played a humongous role in westward expansion, Manifest Destiny, and in indigenous assimilation efforts. It is an essential component to U.S. history that absolutely must be taught in schools.

2. The massacre at Wounded Knee and the AIM occupation

The massacre at Wounded Knee, which resulted in the bloody murders of 250 to 300 Lakota men, women, elders, and children, was a part of a pattern in United States war tactics to quash anti-colonial movements and people. Dunbar-Ortiz says that this pattern would continue “from the Philippines and Cuba to Central America, Korea, Vietnam, Iraq, and Afghanistan. The cumulative effect goes beyond simply the habitual use of military means and becomes the very basis for U.S. American identity.” How can students fully comprehend a history of the United States without first studying this event, which is exemplary of the horrific war tactics employed by the U.S. to eradicate this land’s first people?

Troops were deployed to Wounded Knee in order to arrest Chief Spotted Elk and scatter his followers. Spotted Elk had led a group of Lakota people to Wounded Knee to dance the Ghost Dance, a traditional dance that a Paiute elder had prophesied would bring about the end of Euro-American imperialism. We cannot teach that the United States was founded under the freedom of religion principle when such violent acts are perpetrated against people practicing their religion. It is also important to teach that just 14 days earlier, Lakota leader Chief Sitting Bull was issued a warrant for arrest at Standing Rock reservation, where he would be eventually killed by police.

Important to teach alongside the massacre, however, is the 1973 siege and occupation of Wounded Knee. It is irresponsible to teach moments of tragedy without also teaching the resistance movements which oppose colonial violence. The occupation lasted 71 days and aimed to challenge the substandard living conditions created on reservations by the U.S. government. The choice of placement here was critical; to advocate for social change on the land that had born witness to tragedy is power.

This movement was part of a larger string of protests and occupations known as the Trail of Broken Treaties, which included a 20-point position paper to address the injustices against indigenous people on behalf of the U.S. government.

3. Boarding schools and extreme assimilation efforts

Indian boarding schools were created in order to assimilate Native people by forcibly removing them from their communities, culture, and family. Dunbar-Ortiz says that these schools were modeled after the Fort Marion prison, where Captain Richard Henry Pratt left “captives [shackled] for a period in a dungeon, had their clothes taken away, had their hair cut, dressed them in army uniforms, and drilled them like soldiers.” This is the same man who is famously quoted as saying, “Kill the Indian and save the man.” The Carlisle Indian Industrial School was the first to be implemented under this motto. At schools like these, indigenousness was posed as antithetical to civilization, as though Native people had not created their own civilizations, cities, and communities thousands of years before imperial contact.

More than 100,000 Natives were placed into boarding schools, and the end results included, mostly, irreparable psychological and emotional damage. By forcing cultural imperialism and genocide upon children, the U.S. government made its priorities clear: If Native people could not be massacred out of existence, then the next facet of life to attack was culture, language, and the soul itself.

But indigenous culture is beautiful, brilliant, resilient, and proud. Teaching the traumatic legacy of boarding schools is imperative to taking responsibility for the great harm colonialism has caused. Other ways to ensure that indigenous culture does not disappear is by investing in the success of traditional Native language and buying from inspired Natives rather than from culturally appropriative Native-inspired fashions.

4. The Indian Relocation Act of 1956

This was a Bureau of Indian Affairs-funded project that focused on relocating indigenous people to major urban industrial areas, most prominently to the San Francisco Bay Area, Los Angeles, Phoenix, Dallas, Minneapolis, Denver, and Cleveland.

Indigenous people were drawn away from tribal communities and funneled into urban areas with the promise of BIA benefits, housing, and job training programs. It is important to note that at this time, the U.S. government had already terminated over 100 indigenous nations, making relocation another act of assimilation, another act of trying to make Native people disappear. By further distancing Natives from tribal life and identity, the easier it would be to attack and destroy treaties and legislation upholding tribal sovereignty. The struggles of Natives relocated to large cities are diverse and include poverty, violence, alcoholism, and a loss of tribal identity.

What the U.S. did not expect was for marginalized communities to inspire one another. As Native populations were scattered into poor communities and into existing communities of color, the proximity of Natives relocated to these communities in the thick of the civil rights movement led to the formation of indigenous advocacy groups, such as the Minneapolis-based American Indian Movement.

5. The 1969 occupation of Alcatraz Island

From November 20, 1969, to June 11, 1971, a group of inter-tribal activists under the name Indians of All Tribes occupied the island after Alcatraz Federal Prison shut down operations on the island, citing the 1886 Treaty of Fort Laramie, which guaranteed the return of out-of-use federal lands to Native peoples. After a period of removals, the occupation gained traction and 79 Native activists held the space down, despite a Coast Guard brigade. The Alcatraz Proclamation, a sharp and bitingly pointed document, issued a direct statement of intent to the U.S. government: that since the infrastructure of government-created reservations became increasingly unstable and unlivable, it was only the natural course of things for indigenous people to “discover” new lands to populate.
