Real Crusader History Blog" Dr. Helena P. Schrader reviews "Frankish rural settlement in the Latin Kingdom of Jerusalem" by Ronnie Ellenblum (2003) as quoted below:
"In this seminal work, Ronnie Ellenblum, a professor at the Hebrew University of Jerusalem, challenges the assumptions of prominent 20th-century scholars concerning the composition and character of crusader settlement and society. (...) Ellenblum’s research enabled the “reconstruction” of entire villages ― property by property ― identifying in the process the origins and vocations of many of the inhabitants. This survey turned up roughly 200 Frankish settlements, most of which had never been heard of before either because the settlements themselves had since been abandoned, ruined and overgrown, or because their Frankish origins were hidden behind modern Arabic names and more recent construction.
One of Ellenblum’s chief theses is that: “The Franks…were very successful settlers and were not only fighters and builders of fortifications. The migrants who settled in the Kingdom of Jerusalem established a network of well-developed settlements…includ[ing] the construction of developed castra [towns], of ‘rural burgi,’ and monasteries, of castles that served as centers for seigniorial estates, of smaller castles, manor houses, farmhouses, unfortified villages, parochial systems etc.”
Even more important, Ellenblum proves beyond a shadow of a doubt that the claim of earlier historians such as Prawer and Smail “that the Franks were completely unaware of what went on in their fields (save when it came to collecting their share of the crops), and had no contact with the local inhabitants, is not based on written or archeological sources and is certainly not accurate.” (Emphasis added.) (...) This book makes all previous conclusions about Frankish society obsolete, and any depiction of Frankish Palestine that does not take Ellenblum’s conclusions into account can be dismissed as inaccurate."
