feudalism Detail from the *Heidelberger Sachsenspiegel* showing the homage ceremony, in which the vassals put themselves under the protection of their lords by placing their hands between his hands, 14th century; in the Universitatsbibliothek, Heidelberg, Germany.

In feudal society, subinfeudation was the process by which a vassal subdivided their fief to grant portions of it to their own tenants. By doing so, the original vassal effectively became a lord to these new tenants.12

This practice allowed vassals to expand their own influence and administrative reach by creating a hierarchy of landholding. While the vassal remained obligated to their own superior lord, they gained the rights and duties of a lord over the land they had carved out for their sub-tenants, who were known as subinfeudatories. Over time, as vassals acquired greater rights to alienate their property, this system of layering land tenure became a standard feature of the feudal structure.23
