The idea of french revolution spread …

• The French Revolution is significant for the fact that it marked the end of the institution of absolute monarchy in France and saw the establishment of a Republic. Liberty, Equality and Fraternity, which had become the guiding principles of the French Revolution, also became the foundational values of the French Republic.
• The ideas of liberty, equality and fraternity and the establishment of democratic government helped in the spread of nationalism in other parts of the world. 
• The French Revolutionaries declared French as a common language of France, martyres were celebrated and oaths were taken on the name of the nation. 
• The formal royal standard was replaced by the French tricolour.

All the above measures helped in spreading nationalism not only in France but also in Europe.
