Final answer:
The claim that migration has not significantly impacted Eastern Europe is false. Eastern Europe has experienced substantial migratory movements that have shaped its demographic and cultural outlook, influenced by global historical forces and regional socio-political changes.
Step-by-step explanation:
The statement that historically, migration has not significantly impacted Eastern Europe is false. Eastern Europe has been a region of significant migratory movements, especially during the late nineteenth century with the arrival of southern and eastern European immigrants. These migrants differed from their western and northern European predecessors in a variety of ways, including culture, religion, and socioeconomic status. Over time, this migration has significantly reshaped the demographic and cultural landscapes of Eastern Europe and its social structures.
Historical global forces such as colonialism and the transatlantic slave trade have contributed to migration patterns around the world, and Eastern Europe has not been immune to these influences. In addition, phenomena such as wars, economic opportunities, and political changes have also driven people to move to, from, and within the region, continuing to influence its development up to this day.
