Partition Formalized: Ireland Divided by 1925 Agreement

Three years after the Irish Civil War began over this very question, the signatures went down. The boundary commission had failed — Northern Ireland's borders would stay exactly where they were, six counties carved from nine. Dublin got fishing rights and release from war debt. Belfast got permanence. London got out. But the compromise satisfied almost no one: republicans saw betrayal, unionists saw threat, and 70,000 people found themselves on the wrong side of a line that would spark three more decades of political tension and, eventually, the Troubles. The deal didn't end partition — it made it permanent.
