This period was called Pax Romana which was an era of Roman history marked by apparent peace and prosperity during the transition from the Republican period to the imperial period, which brought stability to the Roman Empire and secured Rome's authority over its provinces. The expression pax romana originates from the official language of the Roman Empire - Latin - and means "Roman peace". The policy of Pax Romana was applied throughout the empire.
The Native American group who lived in movable tepees as they followed the buffalo herds were the Plains natives.
Once the natives gained horses and guns, the Plains Indians became more effective and more mobile. Since they were tied to only the buffalo, they lacked the agriculture.
When Spanish arrived the the 16th century in the southwest, Pueblo Indians were trading their corn for the buffalo meat and hides from the Plains natives.
Before the Plains natives knew it, all the buffalo were gone which rapidly changed the Indian abilities.
