In the broadest sense, the Celts are the peoples who migrated over vast distances throughout the Eurasian continent and prmarily settled and established their culture in the northern and western-most parts of Europe.
Along with their cousin tribes: the Picts, Norse, Saxons, Dacians, Goths, and others, the Celts became defined as "barbaric" and primitive by the Romans. History however provides evidence for the highly developed culture held by these tribes, which maintained personal and social customs which are far more practical and honourable than the current trends of our modern world. Our ancestors created and effectively maintained a Golden Age that legend still recalls.
