Monks Mound at Cahokia in a modern public-domain photograph; one site among many Indigenous histories.

A broad, comparative history of Indigenous North America: peoples, homelands, knowledge, political institutions, colonial encounters, survival, sovereignty and renewal. Inuit history is a substantial strand throughout, not a footnote to the history of the continental United States.

Geographic and historical scope

North America is used geographically: the Arctic and Greenland, Alaska, Canada, the continental United States, Mexico, Central America and the Caribbean. This includes Inuit, Iñupiat, Yupik, Kalaallit, Unangax̂, Alutiiq, First Nations, Métis, Native American nations, Mesoamerican peoples, Kalinago, Taíno and Garifuna contexts. Their identities and institutions are not interchangeable. Innu are distinguished from Inuit; Métis is not used as a generic label for anyone with mixed ancestry. The scope is a selective survey, not a claim to cover every nation, community or event.

The chronology begins with selected evidence of deep history and substantial precolonial agriculture, exchange, cities, earthworks, Arctic technologies, literature and governance. It continues through colonial violence, slavery and forced labor, displacement, treaties, imposed institutions, resistance and state policies, while also recording community control, contemporary art and film, political leadership, language renewal, research sovereignty and ecological restoration. Indigenous people are not treated as existing only before contact or as only the recipients of outside action.

Modern state borders do not delimit the origins of the peoples they divide. A European expedition, colonial charter, purchase between empires, reserve designation or federal recognition is not assigned as the beginning of an Indigenous people. Similarly, leaving a city or transforming a political system does not mean that the people disappeared. Maya, Pueblo and Taíno continuities are made explicit.

Tags and comparison

Every moment and completed duration has people: … tags and a peoples metadata list. These identify named nations, communities, coalitions or carefully labelled historical/archaeological contexts. Archaeological labels such as Olmec, Hopewell, Dorset and Mississippian are not silently treated as exact modern tribal citizenship categories. Broad labels are used where the evidence or event is genuinely cross-regional; they do not imply that every member shares one political view.

Use Separate by tags to compare people: inuit, people: métis nation, people: haudenosaunee confederacy, people: diné / navajo, people: maya peoples, or a specific regional community. The history strand: inuit histories tag joins selected directly related Inuit contexts while preserving their specific labels; region: arctic and subarctic also includes distinct earlier archaeological traditions and Dene contexts. Other regional and topic tags allow comparisons through land rights, treaties, foodways, language, child welfare, cultural production or self-government. These are reading tools rather than claims that all communities in a region share one ancestry or institution.

Useful windows are 22,000–1000 BCE for deep evidence and early regional developments; 1000 BCE–1500 CE for urban networks, Arctic histories and precolonial institutions; 1500–1900 CE for distinct colonial encounters, diplomacy, resistance and dispossession; and 1900–2025 CE for institutions, rights, cultural production and continuing self-determination. The ancient footprint entry makes the full-history view wide, so zoom to a window and separate by people or topic for detail.

Chronologies and evidence

Proleptic Gregorian BCE/CE comparison coordinates, UTC, without a displayed year zero. Year-only events use January 1 solely as an anchor, not a claimed event day. Approximate markers identify broad archaeological estimates or representative phases. Traditional calendars and oral histories are not claimed to originate in this display system. Pre-Gregorian documents generally use year-only plotting rather than silently relabelling an unconverted Julian date.

The timeline distinguishes oral traditions, archaeological estimates, surviving documents and later research announcements. Oral knowledge is not dated to its first written recording. The Great Law and Haudenosaunee foundation are not assigned an invented exact year: the 1722 entry instead dates a surviving diplomatic record. Very old footprints are not assigned a modern tribal citizenship. Scientific revisions are recorded as research milestones without treating modern scholarship as the source of a people’s relationship to land.

Inuit chronology uses a specialist account of earlier Paleo-Inuit traditions and later Thule Inuit expansion, while acknowledging that older public summaries sometimes use different regional dates. The thirteenth-century expansion anchor is approximate. The legal and political events distinguish a signed agreement from commencement and implementation. Nunavut’s public territorial government differs from NTI and from Nunatsiavut’s regional government. Greenland’s self-government is not described as independence. The 2024 Nunavut devolution agreement is recorded as signed, with its later 2027 target explicitly remaining future implementation rather than an already completed transfer.

Sources prioritize Indigenous nations, organizations and institutions where available: Haudenosaunee and Onondaga sources; the Alutiiq Museum; the Gabriel Dumont Institute; ITK; Nunavut Tunngavik; Nunatsiavut; the Inuvialuit Regional Corporation; Qikiqtani Inuit Association; Nisg̱a’a and Tŝilhqot’in governments; Dene Nation; Indigenous-authored art and film histories; and survivor-centered inquiries. These are complemented by primary treaty and law texts, court opinions, archaeological research, public archives, museums and specialist scholarship. Colonial and government sources are evidence of particular positions, not automatically neutral descriptions or the only authorities on an event.

The selection reaches 2024 and uses later historical scholarship where useful. Laws and judgments are described within their scope, without implying that every similar dispute has the same outcome. An apology is distinct from redress, a declaration from implementation, and federal recognition from the origin of a nation.

Definite durations and media

No duration ends at today or the creation date. Three bands mark completed phases only: Carlisle’s 1879–1918 institutional operation, the 1884–1951 Canadian potlatch prohibition, and the 1969–1971 sustained Alcatraz occupation. None depicts the lifetime of an Indigenous people, the duration of a culture or an artificial endpoint for continuing harms and rights.

The cover and backdrop show Monks Mound at Cahokia, one Indigenous engineering and community achievement rather than a visual stand-in for all peoples. Media are individually public-domain, CC0 or Creative Commons works, credited below and beside pictured moments. Modern photographs of surviving places are distinguished from original events. Portraits and a 1998 medal ceremony are not mislabelled as photographs of earlier political actions. The Haudenosaunee image is a modern commemorative plaque, not an original wampum belt or treaty; the SG̱ang Gwaay view is not the Lyell Island blockade. No alterations beyond thumbnail scaling. Contemporary copyrighted artwork is discussed without reproducing it.

Moment details

Separate by tags

Events with any chosen tag move into a track above the rest of the timeline. Nothing is changed or saved.

Shift or scale times

Each time becomes (time − around) × scale + around + offset, exactly, as comparisons align timelines. A duration’s start or end that follows a moment moves with that moment.

        These timelines use different printers or parsers. Choose the display for this comparison. Original times stay unchanged; use scale and offset to align different coordinate conventions.

        Timeline time display

        These settings belong to this timeline and are included in saved files and server copies. Times stay exact.

        Numeric labels are rounded. SI prefixes work best with unit symbols such as s. A Julian year is exactly 365.25 days.

        Displayed value = (stored time − origin) / scale. For Gregorian display, the displayed unit is one second from 1970-01-01T00:00:00Z.

        Preview uses the current window span and viewport width. Custom helpers: hasView(), viewLeft(), viewRight(), viewSpan(), viewWidth(), unitsPerPixel(), labelResolution(), purpose(). Existing printers and parsers can ignore this context.
