Belgian independence and Britain's Scheldt interest

Belgian independence divided the great powers and became the first major test of the Vienna settlement. Wellington rejected Dutch appeals for armed restoration and chose negotiation with France because intervention risked an unlimited revolutionary war. Prussia's restraint then made Russian or Austrian counterrevolution far less likely, while London became the natural site for a great-power conference. The crisis also absorbed Wellington's attention while demands for domestic political reform mounted, and his ministry fell within weeks. Great-power cooperation reflected overlapping interests rather than durable unity or sentiment for Belgium. Control of the Scheldt affected invasion routes, Channel security, and Britain's ability to preserve an offshore balance without occupying the Low Countries itself.
