Prehistoric Europe is Europe with human presence but before the start of recorded history, beginning in the Lower Paleolithic. As history progresses, considerable regional irregularities of cultural development emerge and increase. The region of the eastern Mediterranean is, due to its geographic proximity, greatly influenced and inspired by the classical Middle Eastern civilizations, and adopts and develops the earliest systems of communal organization and writing. The Histories of Herodotus (from around 440 BC) is the oldest known European text that seeks to systematically record traditions, public affairs and notable events. In contrast, the European regions furthest away from the ancient centers of civilization tended to be the slowest, regarding acculturation.[clarification needed] In Northern and Eastern Europe in particular, writing and systematic recording was only introduced in the context of Christianization, after 1000 A.D.
