The Tenures Abolition Act of 1660
In my interpretation of Thomas Wright's account of the History and Topology of Essex I admit that I was a little confused about the "holding" of the land.
I think that the main reason for this is that it was coinciding with The English Restoration.
The Statute made constitutional gestures to reduce feudalism and removed the monarch's right to demand participation of
certain subjects in the Army. By abolishing feudal obligations of those holding those feudal tenures other than by socage,
such as by a knight's fee, it standardized most feudal tenancies of the aristocracy and gentry.
Socage was one of the feudal duties and land tenure forms in the feudal system. "
Inquisition post mortem - according to Wikipedia:
" An Inquisition post mortem (abbreviated to Inq.p.m. or i.p.m., and formerly known as an escheat) (Latin, meaning "(inquisition) after death") is an English medieval record of the death, estate and heir of one of the king's tenants-in-chief, made for royal fiscal purposes. The process of making such inquisition was effected by the royal escheators in each county where the deceased held land. The earliest inq.p.m. was made in 1236, in the reign of King Henry III (1216–1272), and the practice ceased c.1640, at the start of the Civil War, and was finally abolished by the Tenures Abolition Act 1660, which ended the feudal system.
