The emergence of Nation State in Europe

Introduction:
Nationalism is a political ideology that emerged in Europe during the 19th century. It is a belief in the importance of a shared cultural, linguistic, and historical heritage that binds people together and creates a sense of national identity. The emergence of nationalism in Europe led to the emergence of Nation States.

The Nation State:
A Nation State is a country where the citizens share a common identity, culture, and history. It is a political entity that is defined by its borders, its government, and its people. The emergence of Nation States in Europe was a result of the nationalist movement that swept across the continent in the 19th century.

The Modern State:
The emergence of the Nation State led to the establishment of the Modern State. The Modern State is a political entity that is defined by its institutions, its laws, and its bureaucracy. The Modern State is a product of the Enlightenment and the Industrial Revolution. It is characterized by the rule of law, the separation of powers, and the protection of individual rights.

Multinational Dynastic States:
Before the emergence of Nation States, Europe was dominated by Multinational Dynastic States. These were states that were ruled by a single monarch, but had multiple ethnic and linguistic groups within their borders. The emergence of nationalism in Europe led to the breaking up of these Multinational Dynastic States, and the establishment of Nation States.

Alliances formed among many European states:
The emergence of Nation States in Europe also led to the formation of alliances among many European states. These alliances were formed in order to protect the interests of the individual Nation States, and to prevent the domination of one Nation State over another. The most notable of these alliances was the Triple Entente, which was formed between France, Russia, and Great Britain in the years leading up to World War I.

Conclusion:
In conclusion, the emergence of nationalism in Europe led to the emergence of Nation States. This led to the establishment of the Modern State, the breaking up of Multinational Dynastic States, and the formation of alliances among many European states. The legacy of nationalism in Europe is still felt today, as many European countries continue to define themselves in terms of their national identity.
