Guys, may I sugest Brazil? It almost happanned, Dona Leopoldine died at the heights of her popularity and credibility, papers published that D.Pedro should be forced to abdicate and give the crown to Dona Leopoldina who everybody would gladly follow.The proposal was made to her but she remained loyal to her husband. The POD is that she doesn't die in december 1826,and being competly delusioned about her husband and fearing that the Brazilian throne would be lost for her descendants, she was extremely dedicated to service of the country and dynasty,and she accepts the regency. Now depending of the ime of her acceptance we could have ,either D.Maria da Gloria or D Pedro II as the next monarch of Brazil.Dona Leopoldine wanted to Mary her heir to Habsburg cousin,in that case we would get Habsburg Brazil,may be even a new Habsburg cadet branch.Immigration trends would certainly be different than otl!
