Battle for the Channel - What If

There would be no Anglican church, that's for sure. The english would still speak english and they probably would've remained an independant nation, although under a pro-spanish monarchy. The real question would be what would happen to America.

Americans would most likely all speak spanish or french. There would have been no french revolution, and no one would care about english culture, the english language nor english history. Except history buffs like us.

I would take it a step further and claim that the Habsburgs would rule the world. With France just one step away from being conquered, as well as the dutch, this would mean a practically united catholic europe draining resources from all of the colonies of the world. This could only culminate in a holy war against muslims and protestants (possibly russia-but they could prove a useful ally). And thus by 2000 the world is ruled by one government, the Habsburgs........

Perhaps its a little far-fetched but hey it's possible.

there would be cross cultural excahnge, moreso, like English teeth would be better and Spanish food would be worse!  or the other way around.

Despite what is taught in school textbooks, Spain would not have been able to dominate the world after defeating England. The reason why Spain dropped out of the world stage after being such a dominant power is because of its slow response to industrialism. If England, the birthplace of industrialism, were to come under Spain and its slow response to industrialism, the Industrial Revolution would have came from another source. Despite Spain's enduring wealth, it will eventually decline.
