So I was doing research into the European Restoration era and came across Spain's attempted reconquista campaign in the Americas. Now I knew that Spain attempted to retake their colonies after Fernando VII's restoration but didn't realize that at in 1816 the Spaniards had established control of all of their South American colonies. In fact, chances are the Spanish would have managed to keep control if Haiti hadn't given many of the independence leaders, including Simon Bolívar sanctuary and a base to launch a counter offensive.
So lets say those who took refuge in Haiti never make it there: some could be captured, Bolívar could be successfully assassinated in Jamaica or a freak accident sinks ships their on. The point is Spain is able to cement their restored hold in South America. Would this effect what New Spain does? How long could Spain maintain control? Would we see Spanish Dominions emerge in the model of Canada, Australia and the other British ones? Or was such a loss inevitable by 1814 and would only postpone the inevitable?
