No, I am claiming that the Latin rulers became like the indigenous Christians in language, customs etc. Exactly what Fulcher stated.
"This piece of writing, multi-valent, elusive, in some respects contentious, conveys something of the complexities of Frankish identity in the East, the social and economic imperatives underlying immigration, as well as the aspirations of a particularly thoughtful and articulate member of the ‘new’ Frankish community in the East. It also, I think, serves as a warning to historians attempting the task I have been set for today: to offer an overview of the encounter
between Franks and the indigenous peoples of the eastern Mediterranean in the context of the Crusades."
Thanks for leaving me the opening.
