Hey everyone, figured rather than my other (rather huge) question I figured I'd make my first thread somewhat less huge.
Three questions
1) What would be required in order to provide some sort of Britannic Hegemon/Conqueror to unite at least the England/Wales areas if not also Caledonia?
2) Assuming 1) is possible, what else would be needed to enable them to develop ship technology equal to the med empires, but better suited to atlantic waters.
3) Assuming 2), what would the potential effects be if this happened using a POD between Philip defeating Bardylis, and the Punic Wars?
