Close your eyes and picture a map of North America in 1491. What do you see? If you’re like most Americans educated in public schools, you might imagine blank space—perhaps a few teepees, maybe the word “Sioux” floating somewhere in the middle. This emptiness isn’t an accident. It’s the result of centuries of cartographic and educational erasure that have systematically removed one of the most complex political and cultural landscapes in human history from collective memory.
When Aaron Carapella, a self-taught Cherokee cartographer from Oklahoma, couldn’t find a comprehensive map showing Indigenous territories with their original names, he spent over a decade creating his own. The result surprised many. His maps depict more than 1,700 distinct nations spanning North America, each with defined homelands, sophisticated governance systems, and unique languages. As reported by NPR in 2014, viewers often reacted with the same realization: “Wow, there were a lot of tribes, and they covered the whole continent.”
The question isn’t whether these nations existed—they did, inscribed into the land through millennia of habitation, preserved in oral traditions, and acknowledged in hundreds of treaties between sovereign peoples. The question is why, in 2025, most Americans still graduate without ever seeing them. The answer reveals a broader pattern of historical amnesia that continues to shape education, identity, and the ongoing struggles of Indigenous communities for recognition and justice.
The Continent That Was Never Empty
Before European contact, the Indigenous population of North America is estimated to have ranged between about 30 million in the area of the present-day United States and up to 95 million across the Hemisphere, according to more recent demographic research. Estimates vary because researchers use different archaeological, ethnohistorical, and ecological models, but most agree the population likely peaked around 1150 CE before experiencing regional declines. Studies such as the Population history of Indigenous peoples of the Americas and the 2025 Desert Research Institute study provide comprehensive overviews of these varying estimates.
This wasn’t a scattering of nomadic bands. Cahokia, the Mississippian metropolis across the river from modern St. Louis, housed perhaps 10,000 to 20,000 people at its height around 1050–1200 CE. Its central plaza could accommodate thousands for ceremonies, and its trade networks extended across much of eastern North America. In the Southwest, Ancestral Puebloan communities built multi-story stone structures at Chaco Canyon and Mesa Verde that required sophisticated engineering and astronomical knowledge. The Haudenosaunee Confederacy in the Northeast operated under the Great Law of Peace, a constitution predating European colonization that governed five (later six) nations through consensus-based democracy—one that many scholars note may have influenced certain ideas later reflected in American political thought.
These weren’t isolated examples. The Pacific Northwest supported dense populations through salmon fishing and advanced resource management, with complex social hierarchies and potlatch ceremonies governing wealth distribution. Great Plains nations developed mobile governance systems that allowed them to follow bison herds while maintaining elaborate alliances and trade relationships. The Anishinaabe peoples of the Great Lakes region established extensive territories where they practiced seasonal migration, wild rice harvesting, and careful ecological stewardship.
Each nation possessed distinct languages—linguists estimate over 300 were spoken north of Mexico—along with unique governance systems, spiritual traditions, and territorial boundaries. These boundaries weren’t arbitrary. They were maintained through diplomacy, marriage alliances, trade agreements, and, at times, warfare—much like nations everywhere. The Wendat, Tionontati, and Attawandaron of the Great Lakes region built agricultural societies centered on corn, squash, and beans, creating food surpluses that supported large villages and enabled them to weather crop failures. Their matrilineal descent systems granted women substantial political authority, and their diplomatic sophistication was such that both French and British colonizers sought them as crucial allies.
The Cartographic Conquest
The erasure began with maps themselves. When European cartographers drew North America, they employed what we might call selective blindness. Indigenous place names were replaced with European designations. Territorial boundaries recognized by Indigenous nations for centuries vanished, replaced by colonial claims based on papal bulls and royal charters that Indigenous peoples never agreed to. The land itself was redrawn to serve colonial narratives of “discovery” and “wilderness,” concepts that denied the reality of managed landscapes and sovereign nations.
Between 1778 and 1871, the United States government negotiated and ratified approximately ~374 treaties with Native American nations. Most were later broken or altered under pressure from settler expansion. The Smithsonian’s Nation to Nation exhibit documents this treaty history and its ongoing legal implications. Yet even as the government negotiated nation-to-nation, American maps increasingly depicted these territories as empty space waiting to be filled. The land cession maps compiled by Charles C. Royce for the Bureau of American Ethnology in 1899 tell a stark story. Colored sections show how, treaty by treaty and executive order by executive order, more than 1.5 billion acres passed from Indigenous control to U.S. possession.
Consider the case of the Lakota and the Black Hills, or Paha Sapa. The 1868 Fort Laramie Treaty explicitly recognized Lakota sovereignty over the Black Hills, stating that “no white person or persons shall be permitted to settle upon or occupy any portion of the territory, or without the consent of the Indians to pass over the same.” The treaty required the consent of three-fourths of adult Lakota men to make any future changes. Yet when gold was discovered in 1874, Lieutenant Colonel George Armstrong Custer violated the treaty by leading an expedition directly into the protected territory. By 1877, with only about 10 percent of the required signatures, Congress unilaterally passed legislation seizing the land.
In 1980, the U.S. Supreme Court ruled in United States v. Sioux Nation of Indians that this constituted an unlawful taking and awarded the Lakota over $100 million in compensation (now valued at over $1 billion with interest). The Lakota have refused the payment for more than 40 years. As Oglala Lakota medicine man Rick Two Dogs explained, “All of our origin stories go back to this place. We have a spiritual connection to the Black Hills that can’t be sold.” The land was never for sale because, in Lakota cosmology, humans cannot sell what they are part of.
This pattern repeated across the continent. Vague treaty language was exploited. “Impossible” deadlines were imposed and then used to justify military action when unmet. Reservations were reduced through subsequent legislation that tribes never agreed to. And with each land cession, another section of the Indigenous map disappeared from American consciousness.
The Educational Blackout
If the cartographic erasure was physical, the educational erasure has been pedagogical and ongoing. In 2015, researchers at Pennsylvania State University conducted a comprehensive analysis of state education standards across all 50 states. Their findings were striking. Eighty-seven percent of all references to Indigenous peoples appeared only in pre-1900 contexts. Twenty-seven states did not name a single Indigenous individual in their history standards. Many non-Native students, the researchers found, assumed Indigenous peoples had simply died off because they literally disappeared from textbook narratives after the 1890s.
This wasn’t accidental oversight. As education scholar Timothy Lintner notes, history classrooms “are not neutral; they are contested arenas where legitimacy and hegemony battle for historical supremacy.” The decision to omit Indigenous history after 1900 served specific purposes. It allowed American mythology about westward expansion, Manifest Destiny, and the “winning of the West” to stand unchallenged. It avoided uncomfortable questions about treaty violations, forced removals, and what the United Nations Permanent Forum on Indigenous Issues has characterized as cultural genocide through residential and boarding schools.
Joshua Ward Jeffery, who teaches at Navajo Technical University, points out that many students are genuinely surprised to learn Indigenous peoples still exist. They don’t learn that the U.S. Supreme Court has repeatedly limited tribal sovereignty and policing authority. They don’t learn that thousands of Indigenous people lack access to running water or electricity on reservations. They don’t learn about ongoing legal battles over land rights, treaty obligations, and resource extraction on Indigenous territories.
The curriculum distortions go beyond omission. When Indigenous peoples do appear in textbooks, they’re often presented through harmful stereotypes. A 2021 content analysis of U.S. history textbooks found that Indigenous boarding schools—institutions designed explicitly to “kill the Indian, and save the man,” in the words of founder Richard Henry Pratt—received minimal coverage. The Carlisle Indian Industrial School, the prototype for dozens of such institutions where Indigenous children were forcibly separated from families, had their languages and cultural practices banned, and suffered high rates of death and abuse, might receive only a single sentence.
In Texas, Indigenous peoples represented just 4 percent of state history standards as of 2015. California, despite being home to the largest Indigenous population in the United States, did not mandate comprehensive Indigenous curriculum until legislation passed in 2021. The consequences aren’t just educational. As Stephanie Fryberg, a Tulalip psychologist, has described, invisibility has become the contemporary form of racism experienced by Native peoples. When your history, culture, and contemporary existence are systematically erased from the curriculum, the message is clear: you don’t matter.
The Modern Battle for Recognition
The invisibility in classrooms mirrors broader patterns of erasure in American public life, but it has also sparked resistance and innovation. In Oregon, comprehensive legislation passed in 2017 required all public schools to teach Indigenous history from Indigenous perspectives, with funding provided to tribes to develop their own curriculum materials. Washington State’s Since Time Immemorial curriculum, developed through collaboration between the state and tribes, has become a model for tribally specific education, though implementation remains uneven more than a decade after the initial 2005 resolution and subsequent 2015 mandate requiring its use in all districts.
The Smithsonian’s National Museum of the American Indian launched Native Knowledge 360° in 2018, an educational initiative built around ten “Essential Understandings” that challenge common misconceptions. One key understanding directly addresses the mapping problem: “There is no single American Indian culture or language. American Indians are both individuals and members of a tribal group.” The curriculum uses primary sources, Indigenous voices, and accurate historical context to fill the gaps left by standard textbooks.
Individual Indigenous scholars, educators, and activists have created resources state by state. Priscilla Buffalohead, a Ponca educator, explained that she became a curriculum writer “primarily because of my children. I wanted to write curriculum that showed the beauty and integrity” of Indigenous life. The recently developed Indigenous Chicago curriculum represents community efforts to ensure that urban Indigenous populations—which include more than 100,000 Native people in Illinois—see their histories reflected in local education.
Meanwhile, the debate over land acknowledgments has become a flashpoint. These statements, which recognize Indigenous peoples as original inhabitants of specific territories, have proliferated at universities, government buildings, and public events since the late 2010s. Critics within Indigenous communities worry they are becoming routine and performative—words without action. As Cutcha Risling Baldy, an associate professor of Native American Studies and member of the Hoopa Valley Tribe, argues, “The land acknowledgment gets you to that start. Now it’s time to think about what that actually means for you or your institution. What are the concrete actions you’re gonna take?”
Those actions increasingly center on sovereignty. In 2024, tribal nations across the country continued asserting jurisdiction over their territories in new ways. The Nez Perce Tribe expanded its authority in domestic violence cases involving tribal victims. The Forest County Potawatomi Community became the first Wisconsin tribe to win self-governance status in transportation. The Black Hills Visitor Information Center came under joint tribal–federal oversight. In Washington State, BNSF Railway was ordered to pay the Swinomish Indian Tribal Community nearly $400 million for trespassing on reservation land. These aren’t abstract historical questions—they are ongoing legal and political battles over recognition, rights, and resources.
The mapping work continues as well. Native Land Digital, an Indigenous-led nonprofit based in Canada, maintains a growing interactive database of territories, languages, and treaties across the Americas and beyond. Users can enter any address and learn which Indigenous nations historically inhabited that land. The project carefully notes its limitations—boundaries were often fluid, multiple nations might have overlapping or sequential claims, and not all Indigenous peoples held Western concepts of bounded territory. But the act of mapping itself is a form of reclamation.
Aaron Carapella, whose maps opened this article, has said he views his work as correcting a fundamental injustice. Many Indigenous nations were “stuck with names chosen arbitrarily by European settlers—often derogatory names other tribes used to describe their rivals.” The name “Comanche,” for instance, derives from a Ute word meaning “anyone who wants to fight me all the time.” As Herman Viola, curator emeritus at the Smithsonian, noted, “It’s like having a map of North America where the United States is labeled ‘gringos’ and Mexico is labeled ‘wetbacks.’”
Today, more than 5 million Native Americans live in the United States, with about 78 percent living outside reservations. They are citizens of 574 federally recognized tribal nations, each with its own government, laws, and relationship with the federal government. They are lawyers arguing treaty cases before the Supreme Court, scholars producing cutting-edge research, artists reclaiming cultural traditions, and teachers fighting to ensure the next generation doesn’t grow up with the same gaps in knowledge that plagued previous ones.
Maps as Acts of Justice
The indigenous map of North America didn’t vanish because it stopped existing. It was systematically erased through deliberate acts of cartographic violence, broken treaties, forced removals, and educational policies designed to make indigenous peoples disappear from American consciousness. That erasure served colonial purposes; it’s easier to justify taking land from peoples you’ve rendered invisible or confined to a romantic past.
But maps are also acts of restoration. Every time an educator teaches comprehensive indigenous history, every time a student learns that the Haudenosaunee Confederacy influenced certain democratic principles later adopted by the United States, every time someone looks at Aaron Carapella’s map and sees the hundreds of nations that European colonizers encountered, the erasure loses power. The question of whether indigenous history is disappearing has a dual answer. Yes, it continues to be systematically excluded from curricula in many states. And no, because indigenous peoples themselves are ensuring it survives, adapts, and reclaims its rightful place in how we understand this continent’s past and present.
The work of creating accurate maps—both literal and educational—continues. It requires acknowledging that North America in 1491 wasn’t an empty wilderness but a complex landscape of sovereign nations. It demands recognizing that treaties aren’t quaint historical artifacts but living legal documents that define ongoing relationships between governments. It means understanding that when we teach children a history that makes indigenous peoples vanish after 1900, we’re not just getting the past wrong. We’re distorting the present and limiting the possibilities of the future.
The map of indigenous North America is there, waiting to be seen. The question is whether American education will finally let students see it whole.
The deliberate erasure of Indigenous nations from history is a moral failure that enabled displacement, cultural destruction, and marginalization. Acknowledging this history is a responsibility, and ignoring it perpetuates injustice.
This is fascinating 🤨. Thank you!
