Celts

Iit is perhaps not fully realized that French, English and Spanish - different as these three people can be - are all of celtic origin. Conversely, Central European populations, such as Germans, spoke a very differente group of languages. And Celts were ultraviolent, making human sacrifices and terrifying the Romans in their incursion - the conquest of Gaul by Julius Caesar appeared as an almost superhuman endeavour. And possibly this extreme violence is in some way in the DNA of these people, and explains why they colonized practically the whole world, destroying entire civilizations in the America, submitting hugely populated regions such as India. The usual explanation of the uneven distribution of colonialism is that with the discovery of America countries on the Atlantic coast of Europe were favoured; but this doesn't explain why Portugal was satified with a network of harbours, whereas Spanish, English and French submitted entire reigns.
