An origin and social structure, legal and property status, as well as personal and numerical strength of Ukrainian nobility are the main objects of the author's research. The first edition of the book, written at the end of 1980th, was published in 1993.This researh immediately became a bestseller and bibliographic rarity as it inspired a range of further fruitful scientific studies by Ukrainian and foreign historians in the same field. The new edition has been fundamentally revised and updated.
