It's probably been so long that neither really hold the war against each other. The trade route is too profitable and a friendship is more useful than some sort of bitter rivalry.

Sweet. I'll get this all on to my sheet, but summing it up just so we're 100% on the same page:

Some 300 or 400 years ago the only son of the ruler of Arman had died before he could bear children, so the title of heir was to be rightfully given to one of his daughter's husbands, who was the ruler of a region in Azraca. Of course, the Armanians would rather have a more closely associated bloodline from Arhus take the throne, but the lord from Azraca pushed his claim forward with force; this resulted in armed conflict in which he invaded Arman. While the Armanians held them off, their allies in Arhus committed to a counterattack only to find themselves helpless against the unusual tactics of Terusite warriors. Their exhibition was lost, though back on the other front the Armanians found a Pyrrhic victory. This encounter allowed the Terusite military to gain a reputation as being devious; and to solidify a new heir for centuries to come, Arman and Arhus entered in a personal union, the then ruler of Arhus, [name here], now ruling over both Arhus [i]and[/i] Arman.

Nowadays, neither side holds the conflict in bad taste, and many have long forgotten about it. Relations have improved greatly between the Commonwealth and the Dominion; both sides realize that a friendly demeanor between them is both more profitable and useful than holding bitter grudges.

I get everything right?
