For the first time in the “Life of Remarkable People” series, a biography of one of the greatest Russian saints - St. Sergius, the Wonderworker of Radonezh, is published. He was called “Hegumen of the Russian Land” during his lifetime. But Sergius’s life was by no means confined to the walls of the Trinity Monastery he created; he is rightfully considered a major political figure of the era of the Battle of Kulikovo. So what kind of person was this? What role did he play in the history of Russia? What were his moral ideals and political views? How did his relationship with the “powers of this world” develop? The author of the book, the famous historian Nikolai Sergeevich Borisov, based on many years of scrupulous research of all surviving sources, restores the true, and not the legendary, biography of our great compatriot.
