the fall of these colonies in asia and africa will also depend on whether the iberian union takes place as in otl. With this union harming Portugal a lot.So, Portugal is poorer and the dutch can concentrate more on Africa and Asia, so probably Portugal would lose these colonies faster than OTL.
The colony's exports will be agricultural products. In addition to wood for boats.Terra Nova would be a settler colony, pretty agrarian, but knowing how Portugal is, it would become a trade power.
How big do you think the colony would be?About the map, I find unlikely that they would be limited only in these lands.
This map would be the Portuguese colony in 1680+-, I don't see the Portuguese colonizing North America as a whole. Especially when the English start to colonize the region.
Yes parts of the region allow for high population growth especially in the New England region. But first the colonists must come. As @Viriato said "a small founding population of around 500 in the mid-17th century with only 5,000 additional immigrants would have grown to around 750,000 to 800,000 by 1800, if the rate of natural growth had been similar to that of New France or New England ." That would be a good population for the colony. But 800,000 doesn't allow for the colonization of all of North America. Unlike New France, the Portuguese colony will be more populous but not on the scale of Brazil, Mexico or the USA. Allowing them to hold the region, unlike France.They have a big population growth, making them very expansionist, looking for new lands.
This was the situation in New France. On paper the colony was gigantic, in practice it was tiny. The colony was a paper tiger. The Portuguese colony will be smaller but more solid.New France in less than a century, claimed and built lots of forts into the Mississipi-Missouri basin, and this with a smaller population.
A Portuguese colony in North America will not generate a copy of the USA.Terra Nova would just expand into these areas, just with population growth. The same with the Eastern Seaboard. The portuguese will have a century of advantage in these regions. Maybe Portugal grab some Caribbean colonies, but they would just exploit the south.
The colony in North America will not generate the same migration that Brazil generated. The population will grow more due to the climate and good land.But in this TL the people that formed Brazil is now in Terra Nova, and with a bigger population growth and the same thisty for richies. Is very possible for them to go west and find gold and exploit the south.
It is more likely that england, scotland or other power to colonize missisipeConsidering how was Louisiana colonization OTL, the most plausible power to colonize the Mississipi is Terra Nova.
The economy of the colony will be basically based on agrarian subsistence and with low literacy (as seen in new france). The colony can be an industrial power if it makes the right decisions, but it won't be a powerhouse (better an industrial superpower). It will be able to be a great power in the Americas and in the long term be one of the 10 largest economies in the world. The region has potential, but nothing is more common than nations that waste their potential.Is very possible for them to become an economic powerhouse. This colony is basically formed by peasants, traders and artisans, instead of the big landlords and slavers. These type of population usually have much more potential to create a developed society.
