June 1878, Great Britain was troubled with Russia's holding on to so much Ottoman territory in the "Treaty of San Stefano" and forced the parties for a new negotiations with the convening of the Congress of Berlin. The Article 61 of the Treaty of Berlin contained the same text as Article 16 but removed any mention that Russian forces would remain in the provinces. Instead, the Ottoman government was periodically to inform the Great Powers of the progress of the reforms. The Armenian National Assembly and Patriarch Nerses II of Constantinople sent Catholicos Mgrdich Khrimian to present the case for the Armenians at Berlin; in his famous patriotic speech (following the Berlin negotiations) “The Paper Ladle,” Mgrdich Khrimian advised Armenians to take the national awakening of Bulgaria (Liberation of Bulgaria) as a model as the hopes for self-determination were ignored by the European community of nations. In Bulgarian historiography, Liberation of Bulgaria means the events of the Russo-Turkish War of 1877-78 that led to the re-establishment of Bulgarian Sovereign state with the Treaty of San Stefano.
