`  == What is this article about? ==  If this is just about a type of possession why is the article so long? I would suggest the answer  is given in the first sentence ``Allodial title is a concept`` - so it is not just a legal definition it is a concept. Well, what is that concept and whose concept is it? I would propose that the basic themes to structure the article should be: *Origins of the system in Germanic law, what it actually meant during that period *Why it disappeared/changed in some parts of the Germanic world, such as England *The history of the political interpetation, i.e. as part of development of concept of supposed early Anglo-Saxon liberty *Subsequent political use as a concept, such as in newly established USA    `
