@Skadi and Addai's husband -
yes, you both make strong points, particularly the ones about national identity. That's strong to a lot of people.
But there are certainly taxes now in Ferelden - we don't see it in game, but it has to be there in some form. And not every ruler is frivolous with spending. Sure, a lot are, but not all.
For common people, what they want is food on the table, a roof over their head, and the knowledge that they won't lose those things. If that roof gets bigger, if the food gets a little better, to them, that's a good thing. And if you consider the economic benefits of being part of an empire can grant, that's good.
Example - you raise sheep for their wool. You sell it to the weaver in town, who makes cloaks, and sells them in the next town over. Sure, you make a little money. But now sell those cloaks instead to the merchant who will carry them to the Andefels on those roads empires build. The Anderfels is cold, and doesn't have as many sheep. They pay more. Eventually, you make more.
You have a small boat, and you fish a few hundred feet off the coast. You catch your meals, you sell a few extra fish to other people in the village. Now you have access to better wood, or more wood. You build a bigger boat. You now fish a few miles off the coast. You catch 5 times as many fish. You sell a lot more. You make more money. Your children have better clothes, better food, they build more boats, etc.
Empires are not always bad, is what I'm saying. And the little people don't play the Game of Thrones , or
Daes Daemar.
Two other points - Skadi, Ferelden is 400 some years old. That may be young for nations in Europe, but I'm from the USA - that's not a young country, to me.

Addai's husband - sure, language is nice. But offer someone more money, and I bet they'll be willing to learn a new language.
