I think it’s stating the obvious, we are expressing something definitively and clearly.  I stated my case, but it was not good enough to save me from the hangman’s noose.

Or, they stated their case, but with an unforgiving government, it didn’t save them from being deported.

Or maybe not, maybe a state is a territory or nation under one government, though sometimes we might think that governance is not all that great

But it could also mean a subdivision within a single country, like the 52 states of the US, and the 5 states in Australia

And woe betide you if you become a state-less person, it means living in the international transit lounge for the rest of your life.

Or it might be how I feel at the time, you know, I’m not in a fit state of mind to be writing this post, or that I might be agitated, with someone else saying ‘he’s in a state’, or having said something quite odd, it might be said that my state of mind is clouded by grief.

If I was an important person, such as a king or prince, and had the unfortunate luck of dying, I could lie in state, though I could never understand why you’d want to hang around after you died.
