[Twilight] Why don't vampires rule the world?

In most vampire fiction, vampires have weaknesses. At the very least, they're vulnerable to armies and suchlike. Hence why they skulk in the darkness.

Not so the twilight vampires.

They're capable of full on comic-book level superhuman feats, are basically immune to human weapons, can regenerate from being pulled apart and have various random but powerful magical abilities. They're also immune to all normal vampire weaknesses. Sunlight just makes them fabulous, they're very difficult to set on fire, and everything else- garlic, running water, dropped seeds, stakes, crosses, whatever- does nothing.

It's explicitly canon that it's only recently that humanity's weapons reached the point they had any chance- against a WW1 soldier, never mind a medieval man at arms, they'd be unstoppable. So, why didn't they take over the world before then?

They're easily powerful enough to sweep through a medieval army and have a good incentive to keep humans as cattle rather then letting them technologically develop. And it's only the cullens who have any ethical concern about human well-being, and even them not very much.  Why are they skulking in the shadows? At any point prior to the modern day they could have just shown up to humanity and started dictating terms.

So why did they just sit around wandering the woods until we invented the hellfire missile? Why not just take over?

If the vampires take over and turn humanity into cattle, being a vampire becomes mundane. As a vampire you wouldn't be anything special anymore. You wouldn't prowl the night (sparkle the day?) hunting for your victims - instead you'd feed on cattle like shooting fish in a barrel.

The vampire rule would also necessitate a mountain of bureaucracy and a large scale blood farming industry that would take away most of the appeals of being a vampire. You'd still have immortality but you'd lose the freedom that comes with effectively being an outlaw.

The Volturi leaders, for example, are *already* bored out of their mind from ruling just their tiny coven and enforcing just a couple of laws to maintain the status quo. They'd go insane if they had to oversee a world government.

And what if human cattle doesn't work out? You could run into Matrix-esque problems of humans simply not flourishing as blood bags. What about overpopulation of vampires? Wars over blood supply?
