What this map is, and what it is not
- These are the United States' lines, not the tribes'. Royce drew them from the treaties, orders and acts, and from the government's own surveys. Peoples' homelands overlapped and moved, and no nation drew these boundaries for itself. The US Forest Service, which digitised them in 2018, says they are not legal documents and cannot be used to settle title or boundaries.
- The names are the names in the documents. They are often not what a people called themselves. Which nations today descend from the peoples named is for those nations to say, so this page does not say it.
- Not every entry is a cession. Royce's schedule also records reservations set apart, which were often cut down later, and land the United States simply took. For most of Paiute country in Nevada there was no treaty: his schedule says the land was “taken possession of by U. S. without formal relinquishment by the Indians.” Read his entry, linked under each result, before saying what happened to a place.
- The edges are simplified to about a kilometre so the map loads quickly. Royce's own plates, linked under each result, are the record.
- Royce's lines have critics. Of his map of the California cessions, the anthropologist Robert Heizer wrote that it had “no basis for their delineation other than the vague impression of the Senate,” and that “Royce's map is, therefore, his own artifact.”
There are at least three records of whose land this was: where the peoples lived and held it, which they can tell for themselves; what the United States recorded taking, which is this map; and what the Indian Claims Commission later found each people had held, which is on the vanishing map. None of them is the whole answer.
