The Orders in Council were a series of decrees, in the form of Orders in Council, made by the Privy Council of the United Kingdom in the course of the wars with Napoleonic France which instituted its policy of commercial warfare. The Orders are important for the role they played in shaping the British war effort against France, but they are also significant for the strained relations—and sometimes military conflict—they caused between the United Kingdom and neutral countries, whose trade was affected by them.
In Europe, restrictive British trade policy as enacted in the Orders led to the formation of the Second League of Armed Neutrality, and deteriorating relations with other neutral powers, notably Denmark (with whom the British would fight a series of wars) and Russia. In the Atlantic, the Orders in Council were one of the main sources of tension between the United Kingdom and the United States which led to the War of 1812.
Formally, an "Order in Council" is an order by the Sovereign at a meeting of the Privy Council by which the British government decrees policies. It is a political term for a type of legislation that is still used on occasion, particularly in the exercise of the Royal Prerogative.
Especially in American history, the term "the Orders in Council" is also used collectively to refer to the group of such orders in the late 18th and early 19th centuries which restricted neutral trade and enforced a naval blockade of Napoleonic France and its allies. In total, the collective term "Orders in Council" refers to more than a dozen sets of blockade decrees in the years 1783, 1793, 1794, 1798, 1799, 1803–1809, 1811, and 1812; in practice, it is most often associated strictly with the decrees of 7 January 1807, 11 November 1807, and 26 April 1809 which were most inflammatory to the Americans.
