Tribes - The Origins of Humanity

Tribes have a tendency to compete for resources, including territory and prestige. The nation of israel was originally a tribal confederacy where you had a dozen tribes in a kind of loose, family based union. More recently, we've been able to build larger co operative structures like nation states or international alliances. In many parts of the world, people no longer have tribal awareness,. They may have no idea what tribes their ancestors were part of and that they needed to rely on for protection.
