How did the Crusader states tend to view and interact with the Arab and Eastern Christians they lived around and ruled? Did they intermarry? Hire them freely? Did any Arab Christians rise to prestige in these realms?

Finally, what happened to them when the Crusader States we’re finally conquered? Did any move to Europe?

I answered a similar question recently:

What was the social standing of oriental christians in the crusader states of the levant?

To summarize: Eastern Christians had a pretty high social standing, they intermarried with the crusaders frequently, and they often served in the military, as doctors, as merchants, and could become quite wealthy and prestigious.

I don't know if any of them moved to Europe after 1291, but eastern Christians were also prominent on crusader Cyprus in the 13th and 14th centuries.
