Comparing historical records and literary evidence, reprints much of the important 1969 edition of the book, and asserts that: * customary tenants enjoyed legal security in and before the sixteenth century * enclosures proceeded legally, without oppression, and in much the same form (whether ratified in parliament or not) throughout the whole period * depopulation was less extensive than sometimes supposed and that such depopulation as there was often proved economically profitable and not without social benefit. When first published in 1969, this fascinating book represented a unique viewpoint that affected, and in some cases reversed, much accepted opinion. As a landmark work in a highly important area of English agrarian history, it still has considerable impact today.
