The position of Mandalore is part general, part king, all warlord. It is not hereditary and centuries can go by without the Mandalorian clans uniting behind a single ruler. But when one warrior has both the vision and the strength to claim the title, all clans must either recognize his authority or war against it.
Mandalore the Vindicated earned his name through right of conquest, defeating everyone who opposed him. First as a competitor in the Great Hunt, then by toppling his predecessor in single combat and finally by crushing the defiance of the clans who would not stand with him. Today his position is absolute and the Mandalorians have prospered, but few believe that his ambition ends at being a well-paid ally of the Empire.
