STATUTES OF RICHARD II.
In 1390, by a statute of Richard II., it was declared "That no alien person should trade without proof given that he would expend half the value of his merchandise in other merchandise here."
In 1392, after stating that the Free Trade Acts of Edward III. were a great hindrance and damage to cities of the realm, it was declared that "no foreign merchant shall sell or buy within the realm to any other foreign merchant to sell again. That no foreign merchant should sell at retail within the realm, except provisions, and as to some provisions only in large quantities."
