Yes, most of my examples aren't global, but that's largely a function of regulation: the US is the only country with permissive enough economic policy to allow spontaneous monopolies and a large enough economy to be worth creating a monopoly in.
As for historical monopolies on the order of millennia: the modern corporation hasn't existed for millennia and indeed societal, technological, and infrastructural advancement was necessary before we could reach a point where a large scale monopoly was possible. It's hard to run a monopoly by carrier pigeon.
