Don Quixote has been known to everyone since childhood. His name has become a household name, like the name of Sancho Panza. The New Chronology reveals the true essence of the famous novel by Cervantes. Western European reformers of the 16th–17th centuries sought to split the Great Horde Empire and struck at its foundations. For this purpose, in particular, they created the story of Don Quixote as a malicious mockery of Tsar Khan Ivan IV the Terrible, who ruled the Empire in the second half of the 16th century, when a split in the Kingdom was already emerging. Don Quixote by Cervantes is a reflection of that period in the life of Khan-Emperor Grozny, when he became St. Basil the Blessed. The satirical story of Don Quixote became one of the weapons of battle on the political field of rebellious Europe at that time. The reader does not require any special knowledge. All you need is an interest in general and Russian history and a desire to understand its many mysteries. The book is intended for a wide range of readers interested in the application of natural scientific methods in history.
