European nation's land (6)

I believe the answer is:

estate

I'm a little stuck... Click here to teach me more about this clue!

'land' is the definition.
('estate' can be a synonym of 'land')

'european nation's' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'nation's' becomes 'state' (I can't justify this - if you can you should believe this answer much more).
'e'+'state'='ESTATE'

Can you help me to learn more?

(Other definitions for estate that I've seen before include "Property - may go with rank" , "Desmesne" , "One car" , "Everything one owns -- tea set (anag)" , "What you leave when you die" .)

I've seen this clue in The Telegraph.
