In 1396 the Ottomans occupied Bulgaria. It disappeared from the world map, becoming part of the Ottoman Empire. In the XIX century Russian society contributed to the spiritual revival of the Bulgarian people. I.S.Aksakovbelieved that Russia should help not only the spiritual revival of the Bulgarians, but also the acquisition of political freedom, lost in the XIV century.On April 12, 1877, Emperor Alexander II declared war on Turkey. At the cost of enormous human sacrifice, the Russian people freed Bulgaria from slavery, which, after 500 years of non-existence, reappeared on the world map. In the modern press, it can be observed that Russia's role in the liberation of Bulgaria from the Turkish yoke is reappraising. Some scholars believe that the Russian-Turkish war of 1877-1878 was not liberating, but conquering, occupying. The article refutes the opinion of false scientists who seek to distort the truth based on archival documents, as well as on the testimonies of eyewitnesses of historical events (including the testimonies of Bulgarian writers of that time - Petko Rachev Slaveykov, Ilya Blyskov, Vasil Drumyov, Ivan Vazov and others). Ivan Vazov called the Russian soldiers "Knights of Good." P.R. Slaveykov wrote: "Russia has given us freedom with its blood."
