1769 – Following the example of the Philadelphia merchants, Baltimore merchants join the non-importation movement by banning the purchase of English goods until the repeal of the Townshend Acts.
1775 – King George III endorses the New England Restraining Act, which forbids the New England colonies from trading with any other countries except England after 1 July, and also bans them from fishing in the North Atlantic after 20 July. On 13 April the provisions of the act will also be applied to Maryland, New Jersey, Pennsylvania, South Carolina and Virginia when Parliament hears that these colonies have ratified the Continental Association.
