Medieval Holy Land categorization mixed confessional with social criteria unsystematically

Evidence

Here, however, one looks in vain for a systematic methodology of determining the nature of a given category. Why, for example, are the Bedouin treated as a separate religious/ethnic category, even though the term describes neither an ethnic nor a religious group in the same way as does the category ‘Assassins’ (Nizari Ismailis)? In the case of the Bedouin, the categorisation appears to have been made according to urban–rural comparisons of social organisation rather than anything else. — James Renton, Ben Gidley (eds.), Antisemitism and Islamophobia in Europe, 202

Categorization

• QUESTION: Why did the Tractatus separate Bedouin out, given the category doesn’t map to ethnicity or religion cleanly? The urban-rural explanation could be chased across other pilgrimage texts.
