This document provides an overview of the rise of nationalism in Europe during the 19th century. It discusses key events and ideas that contributed to the emergence of nation-states in Europe, including the French Revolution, the Congress of Vienna, and revolutions in 1830 and 1848. It also summarizes the unification processes in Germany and Italy in the latter half of the 19th century. Nationalism in Europe became increasingly tied to imperialism by the late 19th century and caused rising tensions, particularly in the Balkan region.
