Those Children She Has Now and Those She Will Have in the Future Family, Household and Servitude in Medieval France (AD 900 – 1100)

The public lecture will include a Q&A. There will be wine and snacks available.
In the lecture, Dr Ó Súilleabháin will examine slaves, serfs and others who were legally unfree throughout most of the Middle Ages, and who were not captured or trafficked from distance lands, but who were members of the local population, born and raised alongside their free neighbours. This lecture will explore the social realities of the internal reproduction of a system of servitude through the prism of a series of previously unexplored documents from the monasteries and churches of Northern France in the centuries around the turn of the first millennium. It will examine how the institution of marriage was used to ensure a continuous supply of unfree dependents, how unfree status was passed down through children and how family solidarity was expressed, whether in resistance to the demands of lords, or even through the accumulation of inherited offices and wealth within the system of servitude. Finally, it will tackle the broader ideologies used by churchmen to justify their domination over their unfree dependants: the concept of the ecclesiastical familia, a household in which both clerics and dependants symbolically shared. By carefully disentangling the nuances of this concept and its implications, the lecture will shed light on what it really meant to be unfree within a saintly household.
