Protohistory is the period between prehistory and written history, during which a culture or civilization has not yet developed writing, but other cultures that have developed writing have noted the existence of those pre-literate groups in their own writings.
Protohistoric may also refer to the transition period between the advent of literacy in a society and the writings of the first historians. The preservation of oral traditions may complicate matters, as they can provide a secondary historical source for even earlier events. Colonial sites involving a literate group and a nonliterate group are also studied as protohistoric situations.
