The problem with England trying to pass a law like that is that France will demand some kind of compensation for Henry losing his rights to the throne of England and Ireland, which the English won't accept, we might see something like a civil war if the situation grows too out of control... Which I don't think it will but I'm still reflecting on it for a future update.
Well, a law like this is not uncommon, France has a law in this sense, if I'm not mistaken, preventing a monarch from another kingdom from being the king of France (only the opposite can happen). Regarding France demanding something, I find it difficult for England to accept something in that sense, so in theory it won't change much. I doubt that the English will rebel to put a French on the throne, Ireland will probably have more instability. But other than that there won't be anything strange, maybe a commercial or diplomatic agreement (like better treatment of Catholics in the English kingdom for example). More than that will be denied.
Yes Oda wasn't much for Christianity but with the Portuguese being less rabid with their dealings of religion(in Japan and China at least) thanks to "Jesuit thought", it will been seen as acceptable enough. Plus while japan will have it's minority of Christians they will be just that, a minority, even in Kyushu where they will be a very large minority but still be under Shinto overlords and neighbors.
The problem of Christianity in Japan is related to the breakdown that religion causes in the Japanese class system. In Christianity everyone has a soul, in Japan at that time some people had a soul. I find it difficult for Japan to tolerate a large number of Catholics in the long run, especially after unification. Which indicates persecution or a partial tolerance agreement (basically they can live in area x and nowhere else).
Not to mention that with a century or two of cultural differences, many Frenchmen writers and painters and such will be enamored with the (idealized and romanticized) version of the Brazilian culture so it will ironically make it loved by those in the metropole
basically a French tropicalismo (similar to Luso tropicalismo). Regarding the mix, it will be curious to see how the mix goes. In the otl mix people are the largest group followed by whites and then blacks. Due to the population of France being much larger, I think it is likely that the colony has a more European culture than Brazil. But at the same time, the creation of coffee and other products from an early age can demand more slaves than in OTL. So we have to wait and see.
Portuguese actually had a influence in the Japanese language(biggest example being the Japanese "Ne" coming from "Ne" and meaning the same thing really) so with them around for longer will mean there will be a bigger influence.
it also has an influence on the consumption of sweets, such as the fluffy cake japan being inspired by an iberian cake.
And yes Japan actually going into a international route thanks to Oda will make the country stronger, especially because they won't be dependent on the Portuguese and will be doing exploring of their own, especially out East....
the biggest problem for japan in this period is its more than mediocre navy. They had no naval culture or experience, with ships being primarily transport platforms which made it difficult for Japan to project force. In that period, what shone in Japan was the army (which was as modern as the European one).
Is France still interested in the Caribbean now that they have a bigger sugar colony?
I find it difficult to maybe have a small island to do raids, but other than that it is unlikely that they will invest in the Caribbean. Their colony produces everything the carribean produces (usually in greater quantity) and other things like cattle, gold etc.
OTL Brazil already had some Jewish influence, specially in the Northeast under the Dutch, so i definitely can see them having a big community. Although, i imagine they would blend into the melting pot rather than being "isolated" like in the USA.
yes, despite the fact that Jews have historically isolated themselves (or were isolated, both are correct depending on the situation). They will probably be mixed more than in the US, but they will probably not be fully absorbed.
I can see something like Coffee cakes being popular in France as well.
Things with banana and orange in addition to probably similar sweets similar to guava, cajuada, bananada, cocada but more French (probably more worked). In addition to things like candied fruit (which at OTL were extremely popular with the Dutch in Brazil. One author states that the Dutch colony in Brazil exported 109 kegs to Holland in 1631 and 1261 pounds in 1637 of candied fruit, listing other shipments up to the year 1647.)
Brigadeiro would be a hit
yes, but it will probably be a more well-crafted candy. With this abundance of sugar, France probably starts to develop sweets earlier TTL.
They might call it something like "Flemish bred" or even "Parisian bread"
OTl French bread is basically a baguette mine. It was made at the request of people who went to France and loved baguettes, but with no bread it lasted the return trip to brasil. Thus, the bakers only had the discretion of the producer and from that emerged the French bread.
Yeah this basically, France won't need the Caribbean like OTL
At most I see French corsairs having an island in the Caribbean to raid the opponents' colonies. Nothing more than that.
will help in getting business off the ground in the colony, especially when it comes to slave importing alongside sugar, tobacco and sugar exporting, not to mention the fact many of them are of "gentle" professions like doctors, lawyers apothecaries and such will help a lot with the development of the colony not only in the people there but also into getting stuff like the judicial and medical systems in the colony be much more developed which will definitely help out the administration and make more people come given there will be a shift perception from "heathen hellhole" to "barely civilized outpost in the end of the world"
Basically, the colony will have a very robust academic body (ridiculously robust if we compare it to OTL Brasil). In addition to doctors and universities, this will allow France to use the colony as a good base to exert influence on the African coast (and in the long term in Asia).
