I can partially answer this based upon speaking to members of the Navajo Nation. I am not a member of any tribe, and this is just my perception based upon my studies with members of the Navajo Community.

I've posted in the past about Navajo history, and how that history has a strong layer of sovereignty and political issues. Navajo history is certainly a niche topic and even popular topics, such as the Code Talkers, are filled with misinformation at even a basic level. In addition, most Western histories focus on either representing the Navajo as "Noble Savages" or just "Savages". This has long been an issue in history in general but is especially prominent when dealing with American Indians.

In this climate, most Navajo I spoke with tend to view their history separately from the Western historical discourse Most (good) books on the Navajo are published locally on the Navajo Nation, for the Navajo people. Navajo history is taught in Navajo schools, similarly how world and US history are split in the US education system. They are viewed as separate narratives that sometimes collide. Such as the Long Walk of the Navajo.

There are, of course, Navajo academics, and generally interested non-Navajo (me) who are trying to add Navajo history into that Western perspective.

To this day there are a host of political issues that make viewing the two narratives together incredibly difficult. Besides on-going issues such as sovereignty and federal aid, historical issues such as genocide and brutal colonization make that process difficult.

Navajo history is also certainly shaped by Navajo religious beliefs. That is a topic I do not feel comfortable discussing as a very much outsider. I will state that archaeological evidence showing the Navajo migrated to their current area in the American SW in the late 1300s / early 1400s is an incredibly contentious issue among the Navajo due to their beliefs.

Which brings me to the dark side of their reflections. Just like any other history, the Navajo history is constantly being shaped by political forces. The disputes/conflict between the Navajo and Hopi goes back centuries and some members of the Navajo nation like to lean on their historical narratives to discredit Hopi claims.

In summary: The Navajo generally view their history separately from US history and it is shaped by the same political and ideological beliefs as anywhere else.
