The Berlin Decree of 1806 had forbidden French, allied or neutral ships trading with Britain.

By this means, Napoleon hopes to destroy British trade, disrupt its growing industrial expansion and diminish its credit.

Great Britain responds with the Orders in Council of 1807, issued November 11, 1807, as an attempt to channel all neutral trade in continental Europe.

These forbid French trade with the United Kingdom, its allies, or neutrals, and instruct the Royal Navy to blockade French and allied ports.

Napoleon, after Britain' passage of the Orders in Council (1807), retaliates with the Milan Decree, issued on December 17, 1807, which declares that all neutral shipping using British ports, or paying British tariffs, are to be regarded as British and seized.

The decree authorizes French warships and privateers to capture neutral ships sailing from any British port or from any country that is occupied by British forces.

It also declares that any ships that submit to search by the Royal Navy on the high seas are to be considered lawful prizes if captured by the French.

The Treaty of the Dardanelles (also known as the Dardanelles Treaty of Peace, Commerce, and Secret Alliance, the Treaty of Çanak, the Treaty of Chanak or Turkish: Kale-i Sultaniye Antlaşması) is concluded between the Ottoman Empire and the United Kingdom of Great Britain and Ireland on January 5, 1809 at Çanak, Ottoman Empire.

The treaty ends the Anglo-Turkish War.

The Porte restores extensive British commercial and legal privileges in the empire.

The United Kingdom promises to protect the integrity of the Ottoman Empire against the French threat, both with its own fleet and through weapons supplies to Constantinople.

The treaty affirms the principle that no warships of any power should enter the Straits of the Dardanelles and the Bosporus.

The treaty anticipates the London Straits Convention of 1841, by which the other major powers will commit themselves to this same principle.
