Recently I heard an account of the Roman leader Sulla, (138 BC-78 BC) who decreed not only his political opponents but also those of wealthy families should be slaughtered so as to have their property escheat to the state so as to pay his army.
Even today, those without obvious takers of property like children or siblings, nieces and nephews, are at risk for this Roman escheat to the state, unless they have a will of course. However even after the fall of Rome it was not always so.
Things were more civilized by 1066 when Britain was successfully invaded for the last time.
By then it was just a given that when you died, even though you may have paid for the land with a lifetime of rents and military service, the real property of which you were “seized” reverted to the feudal lord.
You really wanted to be a lord then, unless you were King Harold II, who died after receiving a Norman arrow to the eye at Hastings.
All his feudal retainers lost their rights in land to the Norman conquest; William was in charge and started parceling out the country to his army.
Of course sometimes the land was given to the vassal who fought for William with extras, such as adding the term “and his heirs” meaning the knight would be able to leave the property to his children. Thus it was not best to die childless in feudal England however, or the land will escheat back to the William once again.
The record keeping wasn’t all that good the either. Paper was expensive and it took a lot to make up a deed. One had to know Latin, and then find the right rock from the field to represent the transfer to tie to the deed.
If the lord had no paper or couldn’t write, let alone in Latin, typically he would call together the neighbors for a ceremony where he took up a dirt clod from the land in question, and placed it in the hands of the grantee vassal, thereby making the latter “seized” of the land.
Hopefully people remembered whether you were seized of the land for your heirs as well. I guess the take away from this sort of transfer is the vassal wants lots of witnesses, preferably young and healthy.
In consideration for these grants the lord got a share of the crops or other profits from the land.
These ancient dues predated the Conquest, and William apparently liked them so much he just kept the rent the same. Perhaps that is why no one has successfully invaded England since, and loyalty to the Crown remains intact.
Today in the United States you can will your property to whomever you wish, just be sure to do so, lest the lords who govern your state end up with it.
