Still in reverse look-up, I came across irredenta.
Main Entry: ir·re·den·ta

Pronunciation: ir-i-'den-t&
Function: noun
Etymology: Italian Italia irredenta, literally, unredeemed Italy, Italian-speaking territory not incorporated in Italy
: a territory historically or ethnically related to one political unit but under the political control of another
This description made me think of Banda Aceh in Indonesia, though I gather the situation is a bit different...
Anybody know why this term would have originated in Italy in particular? Is it usually applied to other parts of the world?
