It’s never been written about in any book that I’ve found as to who gave these guys the authority or permission to be the international bankers of the world. Why would you even need international bankers? Why would any government agree to use them? Why would you need to use them? Why can’t any country create its own money? It tells you there’s already an existing super structure already in existence, maybe two, three hundred years ago to give these guys permission to somehow be the overlords of all money for all countries.
In 1884 the Fabian Society was formed, chartered by the Crown, with the purpose of ushering in a one world collectivist state through gradualism (versus violent revolution). This would become the basis for what is today called Fabian Socialism.
Fabians also played a large part in the creation of the League of Nations — the forerunner to the United Nations — and were extremely influential in creating the UN itself.
