Milan Decree (1807)

The second Milan Decree, issued on 17 December 1807, expanded Napoleon's maritime enforcement of the Berlin Decree (1806). It declared neutral vessels that submitted to British search, visited Britain or paid British charges to have accepted denationalisation and become liable to capture. The decree was an expired wartime instrument of Economic statecraft.

Rule and context

The decree answered the British Orders in Council (1807) and formed part of Napoleon's Continental System (1806-1814). It must be distinguished from the first Milan decree of 23 November 1807. The second text set tests applied to neutral vessels and treated specified contacts with Britain as grounds for seizure and prize treatment. Conditional language about cessation depended on Britain returning to principles attributed to the law of nations.

The rule strained Neutral rights and duties in maritime war (1856-1909) and exposed neutral trade to competing British and French demands. United States measures, including the Non-Intercourse Act (US, 1809), responded to this environment but did not automatically revoke the French decree.

The decree's strategic effect is contested. It widened nominal denial but also encouraged evasion, false papers, smuggling and administrative discretion. Economic disruption, European resistance and the eventual failure of the Continental System had multiple causes. The decree proves Napoleon's declared policy and legal claim, not uniform enforcement or sole causation.

Capture was not the same as a final prize disposition. Naval or customs seizure, referral, adjudication and sale could occur under different officials and records. Neutral nationality also did not prevent a vessel from being treated as denationalised under the decree's asserted rule. Those distinctions explain why a merchant's loss cannot be attributed from the route alone.
