Under the influence of the great nobles who had unsuccessfully opposed the election of Godunov, the general discontent took the form of hostility to him as a usurper, and rumours were heard that the late tsar's younger brother Dimitri (Demetrius), supposed The to be dead, was still alive and in hiding.
He composed the following operas: Sardanapale (1867), Le Dernier jour de Pompei (1869), Dimitri (1876), La Reine Berthe (1878), Le Chevalier Jean (1885), Lancelot (1900).
At the same time it was displeasing to the Swedes, who had become rivals of the Poles on the Baltic coast, and they started a false Dimitri of their own in Novgorod.
For this purpose Dimitri Donskoi formed in 1380 a coalition of Russian princes, and gained a great victory over Khan Mamai of the Golden Horde on the famous battlefield of Kulikovo, the memory of which still lives in the popular legends.
Already Dimitri of the Don was called the grand-prince of all Russia, but the assumption of such an ambitious title was hardly justified by facts, because there were still in his time principalities with grand princes who claimed to be independent.
