A barbarian warrior could become king of his tribe by proving his strength, leadership abilities, and loyalty in battles and challenges. He would need to gain the respect and support of other tribe members by demonstrating his courage and ability to protect and provide for them. Once he has earned the trust of his people, he could then be elected or declared king by the tribe.
The term "barbarian tribe" generally refers to various groups of people in ancient and medieval times who were considered non-Roman or non-Greek by civilized societies. These tribes, such as the Goths, Vandals, Huns, and Franks, were often characterized by their nomadic lifestyles, warrior cultures, and distinct languages and customs. They frequently engaged in raids and migrations that challenged the borders of established empires, particularly the Roman Empire. The label "barbarian" was often used pejoratively by these empires to denote those they viewed as uncivilized.
