A Query...

[Kuruharan]

This may fall into the "unanswerable question" category...

Was there much in the way of commerce that took place between the Free Peoples and the Men of Darkness (I would have put "forces of Darkness" but I think that direct commerce with orcs would probably have been out of the question).

I started thinking about this question from the perspective of if Gondor had much in the way of ocean going commerce but decided to open the question a little more than that.

Examples that I can readily think of are the intermingling that took place (however grudgingly) between Dunland and Rohan.

I also wonder how the peoples of the East learned about the weath of Gondor. Obviously, they had Sauron to spur them on, but might they also have gained some knowledge through trade...?

Going back to Gondor's maritime commerce, the name "Corsairs of Umbar" implies preying upon Gondor's ships, but were these ships engaged in international commerce or in internal commerce?
