Migration

Can migrations have a positive impact on the people and or land receiving immigrations?

Yes, migrations can have a positive impact on the people and land recieving it. With migration comes trade and exchange. When people move from one area/culture to another they bring along everything that they had or knew with them. So they bring their own culture, techniques, tools, weapons, ideas and knowledge to the empires they are migrating to. The positive impact migration had on empires is that they retained information they didn't know from people who migrated from other cultures/empires. And the end result to that was cultures being mixed and information on weapons, war, and trade was shared. When the first colonists came to North America from europe they brought along their relegion, culture, industrial knowledge and new ideas in general. It impacted America dramatically and changed the culture of the native americans.
