In his book The Continent of the Red Man, Yale professor Ellsworth Huntington states that "history in its broadest aspect is a record of the migrations of man from a environment to another". This quote bluntly conveys the important role that migration has played in history. The migrations of large groups of people represent an important and crucial model in the study of all aspects of history. Never was this more true than in medieval Europe, where diverse groups of people undertook great migrations thousands of miles to all corners of the continent. These mass migrations are central to the history of medieval Europe. Specifically, the migration of the Goths into the Roman Empire altered the course of history, ultimately leading to the fall of Western Rome. Similarly, Muslim migration to the Iberian Peninsula had strong impacts on the religious and cultural atmosphere of medieval Europe as the lifestyles of Muslim immigrants and indigenous Christian and Jewish communities collided as a direct result of the migration. Analysis of primary sources from these times sheds light on the details and impacts of both of these migrations. Together, the migratory habits of the Goths and Muslims served to shape the medieval European continent, giving rise to unique interactions between starkly contrasting cultures and religions. During the 4th century in medieval Europe the Gothic tribes undertook the important task of migrating into the Roman Empire. To understand how this migration affected Europe it is important to understand why the Goths migrated in the first place. Once the reasons for migration are understood, the consequences of migration and the overall impact of those consequences could be completely clear... halfway down the paper...ninsula are just two examples among many that serve to highlight the extreme importance of migrations for the history of medieval Europe. Migrations of large groups of people are characteristics of change, and true to this characterization, migrations caused drastic changes in the history of medieval Europe. The Gothic migration of the 4th century led to the fall of the Western Roman Empire, an event that had repercussions throughout the world. The migration of Muslims to the Iberian Peninsula in the 8th century caused a lasting alteration in the religious and cultural landscape of Iberia. Primary sources these days contain phenomenal information about the effects of these migrations on Europe. The voices of medieval scholars and historians will forever chronicle the importance of this dynamic moment of cultural movement and collision to the history of the Middle Ages.
