The first clear expression of nationalism …

1. Nationalism is a feeling of people within state territory, which makes them develop a sense of collective identity and shares history or descent. This feeling works as a binding force among people.
2. Before 1789, France was under the absolute monarchy. With the French revolution, Monarch was thrown out and a sovereign body of French citizens was established.

This revolution made France the nation-state and made many political and constitutional changes like:

1. The idea of the fatherland and citizen was created to put stress on a community which enjoyed equal rights under the constitution.
2. A new French flag was adopted to replace the former royal standard.
3.  The Estates General was elected by the body of active citizens and given the name of the National Assembly.
4. Centralized administration and uniform civil laws were made for citizens.
5. Uniform weighing and measurement system were adopted.
6. French became the national language of France.
7.  In the name of the nation, new hymns and songs were composed and oaths were taken.
8. Martyrs were honoured.

All these changes give a clear expression of collectivism and gave people true power to shape the destiny of France. Thus, France became a nation-state and the world got a clear expression of nationalism through the French revolution.
