The First Crusade - Primogeniture

by JessIsShort27

Hi! I have what feels like an impossible History assignment and was hoping for some help. My prompt is:
Though often taught as war between religions, the First Crusade is no longer seen as such by historians. Instead, one emphasis is placed on the availability of land and inheritance laws (primogeniture). Discuss how it contributed to the launching of the First Crusade; be sure to support your answer with specific examples from scholarly peer-reviewed sources.

I've been looking for two days and cannot find any "scholarly" resources on this. I can barely find any material on it in general. Could anyone be of assistance? We are not given reading materials for this; we have to go research on our own. We are not permitted to use textbooks, encyclopedias, .com sites, .org sites, or anything that is not peer-reviewed.

Any help would be appreciated!

Hi - we as mods have approved this thread, because while this is a homework question, it is asking for clarification or resources, rather than the answer itself, which is fine according to our rules. This policy is further explained in this Rules Roundtable thread and this META Thread.

As a result, we'd also like to remind potential answerers to follow our rules on homework - please make sure that your answers focus appropriately on clarifications and detailing the resources that OP could be using.

Additionally, while users may be able to help you out with specifics relating to your question, we also have plenty of information on /r/AskHistorians on how to find and understand good sources in general. For instance, please check out our six-part series, "Finding and Understanding Sources", which has a wealth of information that may be useful for finding and understanding information for your essay.
