French revolution is important part of French and European history, but also societies evolution of western civilization. Time of 18th century in France was the center of new ideas, new political studies and it was marked the century of French educators based on idea of natural law. Social organization and current norms were easily coming to the end (feudalism), instead of them new social organization (capitalism) started to emerge. At the time, Frence was the most populated country in Europe, decorated as an absolution monarchy. During the period of revolutionary changes, we had two conflicting sides. One of them represented old social order opposing to changes and enjoying the privileges of the current regime, while other one is being represented by supporters of new ideas which were led by writers and philosophers about equality, freedom, fraternity, nation and religion, trying to accomplish spiritual revolution and organize protest against absolutism and feudalism (direct the people in a fight against old and residual understandings of sociaty and state). A significant difference beetween two conflicted sides, with all other events (bad financial condition, wars, bad economic situation and ideological - enlightment ideas) was the cause of revolution of Franch society. Revolution by itself as the symbol of principle of democratization and the will of the people existed only in theory, because in that time there was not an established, stable arrangement and there was always dictatorship in force, but in different shape. However, the positive consequences of the movement like the extinction of the absolute feudal order, personal unfreedom of the people, privilege of the nobility and clergy, expanded in the Europe. Thanks to Napoleon's conquests in Frence and other conquered countries, nationally it was coming as awaking time of consciousness and of nationalism by itself which are leading wish of some countries to achieve equivalent revolutionary change. Despite of big political instability during the revolution (1789. – 1799.) and big rooted changes caused by it , after 100 years we can feel the real changes and balance. French revolution was the biggest civil revolution ever in the world, the institution of monarchy was eradicated, aristocracy and ruling of church, feudalism destroyed until foundation and new state was built, introducing the principles of democracy and national sovereignty.
