Liberation of Bulgaria
The Liberation of Bulgaria is a historical process as a result of the Bulgarian Revival. The beginning of the process is disputable as a consequence of the dispute over the beginning of the Bulgarian Revival, but it is generally accepted that this was the year 1762 of the writing of ″Istoriya Slavyanobolgarskaya″. The historical process took on a cultural dimension – a political one in the 1830s and quite clearly after the Tomos dated 29 June 1850. After the Crimean War, the armed struggle for independence in various forms began. The culmination of the process is the April  Uprising. It is symbolic that the national holiday of Bulgaria is March 3 or the day of the signing of the Treaty of San Stefano, and it is no coincidence that under the direction of Count Nikolay Pavlovich Ignatyev was signed exactly three centuries or 300 years after the hanging of Michael Kantakouzenos Şeytanoğlu. Unification and independence. On 6 September 1885, Eastern Rumelia became part of the Principality of Bulgaria after a bloodless unification, although the principality was a "de facto" independent nation but "de jure" vassal nation of the Ottoman Empire until 1908, when Bulgaria proclaimed its declaration of  independence. The 1908 declaration, which signified Bulgaria's break with the Ottoman rule, was actually the second liberation of Bulgaria. After the conquest of the First Bulgarian Empire in 1018, the first liberation of Bulgaria led to the establishment of the Second Bulgarian Empire in the aftermath of the Uprising of Asen and Peter against the Byzantine Empire in 1185.
