40 years have passed since the "Brezhnev" Constitution of the USSR of 1977 was adopted. The history of its creation stretched over many years. What was the reason? How did you "expect" the adoption of the Constitution in those years when work on its draft stopped? Who took part in the creation of the Basic Law of the country? Is it "Brezhnev" and what role did the country's leader Leonid Brezhnev play in its development? How did the creators of the Constitution want to consolidate the role of the CPSU in the infamous article 6, which was subjected to fundamental changes already in the years of "perestroika"? What institutions of the state system wanted to revise? How did ordinary citizens perceive the work on the Constitution in their letters and speeches? About these questions and also about why the Constitution of the USSR of 1977 became the last in the history of "the Country of Councils", invites the reader to think the author of the book, the master of department of history of state and law of law department of Lomonosov Moscow State University Ilya Strekalov.
