RE: Kingdom vs Empire

Does that mean westeros is full of empires more than kingdoms?

Nymeria’s conquest of dorne led to a polity composed of multiple ethnic groups and cultures, there is the first men, andal, and rhoynar or the division between, stony, salty, and sandy dornish. That seems to be an empire.

Likewise, the Gardners realm was said to be made of four seperate kingdoms (arbor, hightower, marches, and reach proper).

The North has the mountain clans, the ‘regular’ northmen, skaggos, the craggomen, and the southerns from the manderlys.

The vale, has the andals and andalized first men, the mountain clans (though they are rebels) and the sistermen.

The riverlands has two different religious groups.

And thats not even mentioning the stormlander and both ironborn empires.

Plus of course the Targaryen realm. 

Also, I find that many people, including myself, have this perception or disposition to think or view empires as somehow ‘better’ in someway than kingdoms (though definetely not necessarily morally better). Would you care to comment on this belief and how it holds up to scrutiny?

To answer your last question first, I don’t see why empires would be considered “better” than kingdoms. They’re not more efficient or effective as political structures – the sheer coordination issues that crop up in empires alone – they don’t lead to more political stability or internal peace, etc. etc. 

I would push back a bit on your descriptions above: 

• Nymeria could have been said to have conquered an empire, if she and her dynasty hadn’t made it a central policy to eradicate all differences between her subjects in the name of creating a common Dornish identity. 
• The Gardeners might have been considered Emperors if they had left the Kings in place instead of absorbing them into one Reach. 
• The North’s divisions don’t come close enough to constituting different nations – with the exception of the Manderlys, they’re all First Men, they all worship the Old Gods, etc. 
• The Vale either forcibly assimilated or excluded the First Men from the polity, so they don’t reconize multiple peoples. 
• Two religious groups in the Riverlands isn’t enough to distinguish two “nations” in the sense of peoples, not without a lot more religious division on the level of the Thirty Years War.

What you could say is that, by claiming to be the “King of the Andals, the First Men, and the Rhoynar,” Aegon implicitly claimed an empire in Westeros, although hasn’t used the title (or indeed an imperial crown).
