Add to this one more nugget of information from the Ecology of the Dragonborn article in Dragon #365:
"Eventually, the expanding borders of the fiendish kingdom of Bael Turath, ruled by tieflings and devils, collided with those of Arkhosia. ... War was inescapable. It came swiftly and brutally, and it spanned hundreds of years."
So, it might have started about 900 years ago, but it ended centuries later, possibly 700-600 years ago.
Good catch. I'm a bit surprised at that, I didn't think the war(s) lasted that long.
