Much of the history of pre-modern European society was shaped by the migration of various groups of peoples into and across the European landscape. The Celts moved from their homeland in Central Europe and settled throughout much of Western Europe, bringing their language and culture with them. The Romans were yet another migrant group, and undoubtedly one of the most culturally impactful groups because they enforced their political, legal and religious customs in the territories they settled. Similarly, the German-speaking tribes who moved into Roman territory as the Roman Empire fell; the Vikings, who emerged from Scandinavia in the late 8th century CE and settled throughout much of Western Europe; and Muslim peoples, who emerged from the Arabian Peninsula in the mid-7th century CE and settled in Spain and Sicily, had a significant influence on the formation of early European culture. We'll examine all of these groups and their impact on the history and culture of Western Europe in the pre-modern period.
