Carthagineans colonize Cuba, Bermuda, Azores, and other Atlantic islands...but...

Presuming Carthaginean colonists set up viable colonies across the Atlantic, perhaps only via one-way trips, how do you think they would evolve and might Rome try to go after them? Do the Carthagineans expand enough to consider a return to the Half-Earth Sea at some future point?
 
Depends on whether Rome obtains similar naval technology. And whether the descendants of the Carthaginian colonists even consider Rome a foe, and vice versa. The colonists would most likely mingle with the natives, and would lack the large technological advantage in weaponry our TL colonists had.
 
I think we have to look at the Cartheginian's naval capabilities before assuming they can get to and colonize Cuba and Bermuda. Azores is definitely a possibilities and so are canaries, but you have to reduce the threat of Rome dramatically for large expeditions to happen.
 
Even if the expeditions were made in desperation or were unintentionally landed in the Americas? Perhaps the Azores and Bermuda are colonized, become jumping off points, and burned by the last surviving Carthaginean ship(s) to pass through?
 
IMO, there are quite a few assumptions which would require Rome to "go after" these colonies mentioned.
  • Rome had the naval technology and inclination. Was not Rome very much of ashore hugging navy?
  • These colonies were able to trade back to Carthage and therefore became an point of interest /envy of Rome.
  • Depending on which islands were colonized, the ability to smelt ore would be limited which decreases the forged components on these sea going vessels.
As for how these colonies would develop, this would be very much dependent upon whether the return journey could be realized or desired.
 
The Norse peoples who colonized Greenland had better technology than the Carthagenians and yet they had a heck of a time with the natives (actually the "natives" of Greenland were there second, the Norse were there first). So I'm not sure if the Carth descendants can do much better in a higher density populated place like Cuba. Bermuda was never inhabited by Native Americans, so better chance there, however in OTL it took 100 years from first being discovered (1507) to being settled (1609), so I'm not sure how easy it is to settle without nearby places being able to send supplies and help. Oh, and hurricanes occur, one bad one can make it unlivable and wipe out methods of leaving. If Bermuda is colonized, then "Virginia" to "Florida" discovered, perhaps they can trade and learn maize cultivation. New York Harbor would be a perfect Carthagenian playground, exactly what they like to see, you could see multiple city-states erected complete with temporary alliances and wars play out in the Harbor as seen in the Greece among the Greek states, with the Hudson Valley and Iroquois being influenced by their technology and customs and ideas of Empire, you might see a more powerful Iroquois form, or the nearer Algonquin tribes might stop the Iroquois from forming in the first place with the help of the Carthagenians. Either way, just as the Hellenized Macedonians learned, assimiliated, and eventually subjugated the Greek states, the same will happen with the Native Americans to the Carths. A Native American empire will form in the Hudson Valley, and take the Harbor, then move west along the Mohawk Valley, and there might even be an Alexander or Chengis like figure who attempts to go as far as he can west in the Ohio Valley and eventually (maybe upon seeing the great Mississippi River?) has to turn around or dies.

Awesome ideas.
 
The Spanish, English and French headed west because the Eastern Med, and its trade routes, were closed off to them. Further, both the English and the Spanish had relatively secure borders with the channel and the Pyrenees. With so much open land nearby, there really isnt much incentive for the Carthagenians to head west. And there is Rome...
 
Eh. It's most likely that these Carthaginian colonies turn on the metropole and redirect their merchants to Rome in an alternative Punic War. After all, Utica and a bunch of other cities betrayed Carthage during the Third Punic War; hypothetical trans-Atlantic autonomous cities? More so.
