How did migrations in this period compare to earlier periods?

People could more easily migrate on a global scale, and people were able to migrate long distances across oceans in addition to land. As opposed to clans and kins migrating to follow large animals or prey for hunting and survival in Period 1, tens of millions of people migrated in this period to find opportunity or to escape misery, both brought by imperialist states. Transoceanic empires, such as the British, made overseas travel much easier with their control of water routes.
