A Lancastrian Castile?

So this is something I've been wondering about for a while.

Let's say john of gaunt and Constance of Castile have a surviving a son and that gaunt is successful in taking Castile, what would the effects of this be?

Would this butterfly away Henry of Bolingbroke exile and subsequent usurpation?

What would gaunt be like as king? And could we see a marriage between his son and Beatrice of Portugal?
 
It depends whether Gaunt's influence got Bolingbroke's sentence reduced from execution to exile.
Assuming Henry still ends up exiled he'll probably go to Castile. This will impact his return after his father dies and Henry wants his inheritance back.
If his return is as OTL then the noticeable changes are probably with the resumption of the HYW as England now has both Castile-Leon and Portugal to back them.
 
I'm not sure it'd necessarily be Henry of Bolingbroke, but isn't it possible some of the Lancastrian kids relocate to Castile of their own volition to chase the opportunities provided by a royal father or half-brother? Though I imagine the local Spanish aristocracy might get uppity if they see too much favour given to English interlopers.

How much would John's absence in Spain affect the reign of Richard II? It seems unlikely that the Bolingbroke exile and usurpation would happen the same way as OTL, given butterflies and all that.

Hmm interesting, would Henry be so bold to claim the throne here?

I agree, I think perhaps some of the Beaufort might shift to Spain for some glory if possible.

And I think there’d be minimal reapparochmenf between different factions I think if John is in Castile long term. Though Richard might not be so brash about Henry

Well, OTL he didn't claim until Richard was dispossessed - his stated position on landing was for his inheritance that Richard and attainted him for (Lancaster, Leicester, WDerby, Hereford) - so I see no need to massively change things there.

This is very true, of course one has to wonder, would Richard dare doing that here, what with John of Gaunt having been King of Castile, and arguably England's biggest ally

Indeed. It might just be that he exiles Henry with a note for John to take him in hand. Of course without his father's influence Henry might have got himself killed, or even been with him in Castile while someone else stewarded the Duchy. And if John is King he might have formally passed on his Stewardship of England to Henry directly thus changing how the court reacted to Richard's rule in the first place.
Lot's of butterflies possible!

Oh this is very true.

Would it be more interesting for Henry to have been given the stewardship once John is secure on the throne, with Henry playing a more cautious line as a result?
 
In terms of alliances I can see this Castile being firmly Anglo aligned at least under john of gaunt and perhaps his son by Constance
 
Maybe. Perhaps a Tri-partite alliance between England, Portugal, and Castille?
That would likely push Aragon into the French Sphere, or perhaps force Aragon to become a dominant Italian player?
Oh that sounds juicy, I can see john of avid fighting a war though as he did otl unless there's a marriage between him and one of John of haunts daughters

Possibly yes. If John of Gaunt and his army don't stop in Brest to support the English, but make haste to Galicia, then we may see him succeeding in his war. It's that simple.
 
I basically did this scenario in The Dead Live, though it was a forceful conquest of Castile by the Lancastrians. There is a lot of potential for drama in the idea and I personally had a lot of fun with it.

The alliance between the Avis and Lancastrians is particularly fascinating and if John of Gaunt had been just a bit more in a hurry they would likely have come to play a major role in Lancastrian Castile. The major question becomes one of what happens with Aragon and how do the French react to the sudden flipping of Castile from neutral/leaning-French to firmly English-aligned?

Agreed, and I think the French would panic, especially if englsnd also becomes Lancastrian they might try and hope Richard ii remains on his Throne

Building in from this, could we see pressure for Richard and Isabella to have children? And funding to remove Henry?
 
I’m also thinking that John of Lancaster will marry Beatrice of Portugal. And in order to prevent a succession war, either Philippa of Lancáster marries John of Aviz or it is agreed that John and Beatrice’s second son will inherit Portugal
