Barbarians

Recently I have rekindled my love of history. Of course this has only reminded me that history can be pretty subjective. For instance there are a lot of groups who have been considered barbarians. Yet in hindsight barbarians were really any group who had different views than you. Which based on current American history books means people different than Romans. However many of these barbarians had their own developed culture, laws and religions. The biggest evidence of them matching the perceived view of a barbarian is that most had no writing system of their own, however considering that most were nomadic there is always the chance that writing systems have just not survived.
Thinking about it in a new light settlers of the Americas would be considered barbarians. In both cases people migrated to a land where others lived and conquering them due to goals such as gaining wealth, being persecuted, or just to start a new life. And in both cases settlers learned from The biggest difference I see is that Native American nations were not united and did not direct the new groups to attack each other as Rome had.
