War generally follows the secession of a member of a union, and the seceding state, being weaker, is usually conquered and the union more firmly consolidated.
This distinction was emphasized during the Civil War between North and South, the seceding states forming a Confederation (Confederate States of America) in opposition to the Federal Union.
In 1876 the general body of the Reformed Presbyterians united with the Free Church of Scotland, leaving the few seceding congregations as the representatives of the principles of the Cameronians.
He had prepared a sustentation fund scheme for the support of the seceding ministers, and this was at once put into successful operation.
The "resumption" by the seceding states of the coast defences (built on land ceded by the various states to the Federal government, and, it was argued, withdrawn therefore by the act of secession) brought on the war.
