What was one significant outcome of nationalism in nineteenth-century Europe?

The unification of small kingdoms into larger nation-states

The correct answer is Option 2 - The unification of small kingdoms into larger nation-states

Nationalism in the nineteenth-century Europe led to the merging of small kingdoms and principalities into larger, unified nation-states. This process resulted in the formation of countries like Germany and Italy.

Nationalism has passed through many phases. For instance, in the nineteenth century Europe, it led to the unification of a number of small kingdoms into larger nation-states. The present day German and Italian states were formed through such a process of unification and consolidation. A large number of new states were also founded in Latin America. Along with the consolidation of state boundaries, local dialects and local loyalties were also gradually consolidated into state loyalties and common languages. The people of the new states acquired a new political identity which was based on membership of the nation-state. We have seen a similar process of consolidation taking place in our own country in the last century or more.
