Congress of Berlin (1878) and the Balkans explores one of the most significant diplomatic events in late nineteenth-century Europe. Following growing tensions in the Balkans and concerns over the declining Ottoman Empire, European leaders met at the Congress of Berlin in 1878 to prevent conflict and reshape the political map of the region. Students examine the causes, outcomes and long-term consequences of the Congress, including the division of Bulgaria, rivalries between Russia and Austria-Hungary, the strategic importance of the Balkans, and the alliance tensions that contributed to future instability in Europe.

This PowerPoint presentation helps students develop a solid understanding of how diplomacy, nationalism, imperial competition and great-power politics shaped Europe after 1871. Through structured discussions, collaborative learning and essay-planning activities, students explore differing historical interpretations and evaluate whether the Congress was a success or failure in maintaining peace and stability.
