Yeah it survived but was never a major power - not in the way that France, Prussia, Austria, Russia, Germany, Persia, the Ottomans, etc etc were.
You got to be kidding? Venice was not only a major power, it was hegemonic. That's why everyone attacked it in conjunction together in 1509.
It just wasn't a land power. It was a naval superpower and to which (as is commonly conjoined) made it a commercial and financial super and had the rest of the world in its pocket. Its reach was far greater and its power much larger than most of the powers you cite above. In its heyday, Venice was the unparalleled center of the world - a level that Paris, Berlin, Vienna nor Moscow ever reached.
The fact is, only one naval power has ever become a genuine superpower - and that was based on the fact it owned a gigantic landmass, namely the Indian subcontinent. The Royal Navy alone didn't conquer India, without a decent army it would have been useless. When the UK lost its Empire it became a third rate power and would have remained so even if it had maintained a gigantic navy. The USSR has no navy to speak of and was a superpower. The USN is clearly a major asset to the US, but it never became a global power until it built a decent army.
It didn't need a gigantic army. Just ships. You use local armies to the bulk of your fighting for you.
The fact that you cite how naval powers can have their navies sunk by other naval powers and then be easily destroyed by land powers is not a point you want to be making. It just illustrates how fragile a sea power is. One major naval battle gone wrong and a sea power can cease to exist. Land powers like Russia, Germany, China, etc have survived enormous catastrophes and still lived to tell the tale.
That is a drawback. But that's a general drawback of imperialism. Far-flung dominions are always susceptible to poaching by a better-armed, better-financed, better-organized naval powers.
But notice not the reverse. A land-power can take a single colony of a naval power, but they won't cripple the naval power. They're fine. They'll be back in a few months later, with stealth and more firepower than you can handle, and likely get it back and pay your relatives to overthrow you.
It is easier to defeat a land power than a naval power. You have to have the ability to reach it everywhere, i.e. be a naval power yourself, or at least have their capital and arsenal within striking distance. By contrast, land powers are stationary ducks.
The Brits can reach and hit Bengal anytime. But Bengalis can't reach London at all. That is not because of land technology. It is sea technology.
Navies can be rebuilt. Roman navy was sunk every year by the Carthangians, but they just built another one, then another one, then another one.
Take your example. The Ottomans destroyed the Venetian navy and this did for Venice. Had the battle gone the other way and the Ottoman navy been destroyed, would that have been the end of the OE? No, it wouldn't, because they still had a gigantic land empire.
Possibly. It has happened before where land-based states lose one big battle - lose one leader - and splinter into warring parts.
Where was Napoleon's land-based empire after the Moscow campaign?
Really? Russia, Germany (in all its forms), China, France, Persia, Austria, The Ottoman Empire, The Arab Empires, The Mughal Empire, The Mongolian Empire, the Roman Empires etc weren't persistent? They hardly survived the death of a charismatic ruler? They all had hundreds of years of enormous power, far more than Venice, The Netherlands or Genoa ever came close to.
No, they weren't. Your confusing the geographic area for a state. I might as well say the Mediterranean Sea or the Indian Ocean has also persisted in some form or another.
The point is precisely the form. If the Russian state collapses to the Mongols, or breaks into multiple pieces, or is overrun and vassalized by another state, then it has ceased, and it is not persistent.
