Who was the land taken from?

The people living there.

I think this was pretty clear from the context of what the commenter said when they referred to the "nations" from which the land was taken.

In terms of, you know, the people who had been living on that land peacefully for more than a thousand years.

Not from the various dying empires that temporarily occupied that land, and pretended to "own" it.
