A supporter or follower of Richard Cobden's principles of free trade and free commerce.
From Cobden's name plus -ite (suffix denoting a follower or adherent). The -ite suffix parallels terms like 'jacobite' or 'yorkite' for political adherents.
Cobdenites believed that free trade between nations would prevent wars because countries wouldn't fight neighbors they traded with—they thought commerce was literally a peace-builder!
