The story

By surface analysis, tribe + -al, first attested in the 1630s. The specific adjectival sense under the defunct theory of recapitulation derives from tribal history as an overly literal learned borrowing from German Stammesgeschichte; ordinarily, Stamm would only be translated as tribe when used in its ethnographic sense.disputed Scholars disagree here; the competing view is quoted as the source gives it.
