Upon further research, it seems like The Phoenicians may have had minor trading operations in The British Isles but The Greeks probably had them as well. Britain even appears to be a name that The Greeks gave the Island. So now I'm also wondering about a timeline where there are Greek Colonies in Britain, maybe Alternate Colonization/Invasion of The British Isles could even be it's own thread since even in OTL a bunch of people invaded the Island (The Angles, Jutes, Saxons, Romans, Danes, Normans, ect.)
