I wonder about the idea of globalisation starting with the empire builders from 15th Century onwards. Was the Roman Empire an example (probably not the first) of a form of globalisation of the world as it was known at the time? I am not sure when international trade began but I imagine it began with very early civilisations.
I would agree that the speed with which information (and non-information) travels today is an important change. The relative ease of travel and transportation is another factor which facilitates the movement of goods and people; and there are many more people in the world than there were, even 125 years ago.
Major international companies have major influence now, directly and through political power; but this is not new. The East India Company is just one example of one from 1600 or so.
I am not sure whether the actions of voters in one country are influenced directly by the voting behaviour in another; but where both electorates are influenced the same global influences, they might move in the same general direction.
