Question

what is result of french revolution

Answer 1

The most concrete results of the French revolution achieved in 1789-1791, when land was freed and the old corporate society was destroyed. This “abolition of feudalism” promoted individualism and but probably retarded the growth of a capitalistic economy.

Answer 2

French Revolution thereafter invasion of France by European powers to support Royalists , then rise of France and invasion of  Austrian Italy rise of Napoleun and Fall of Napoleun these all are considered after effects of French Revolution so accordingly I will answer the question.
1. Most important effect was blow to monarchist system of governance.
Republicanism was order of the day. All monarchies were under threat. They were ready to give concessions to citizens. Powers of kings were curbed like English, French etc.
2. Fundamental rights of citizens like Freedom, Equality and Liberty got a boost. These were basics upon which modern Europe is built
3. Catholic Church got its biggest blow. Mass killings of clergy, looting and auctioning of Church property meant they can never rise again.
4. Rise of Nationalism. Unification and Rise of Germany and Italy was result of French Revolution.
Idea of Nation states got its roots in French Revolution.
Before this states were made at the fancies and whims or marriage alliances of kings and their progeny. But now people have a say in this.
5. Fall of Austria Hapsburg( Holy Roman Empire) 
6. Rise of Britian as world power for next centuryHundreds of thousands of dead French people - mostly quite ordinary in terrible wars and savage internal repression (see the works of William Doyle on the French Revolution). And vast numbers of non French people also dying.

The internal repression and murders were there from the start, as was the plundering (first of the Church - then of anyone the ruling faction of Revolutionaries at a particular moment, dislikes) and the fiat money (“accept this worthless paper as payment for your stuff - or we kill you”). Order was not really restored till the time of Napoleon - and whilst he brought an end to the internal savagery, he committed France to wars to conquer all of Europe (and beyond) wars that were beyond the strength of France and led to the deaths of vast numbers of French people - and others.

More broadly the French Revolution led to the rise of nationalism - “the French dominate Europe because they are united under one ruthless government - if we Germans [or Italians - or…..] were united under one ruthless government, we to would be powerful”.

The obsession with Italian and (especially) German unification in the 19th century is hard to imagine without the French Revolution and the DECADES of wars it produced. Whether this is a good thing or a bad thing - depends on one’s view of German and Italian “unification”.

It used to be fashionable to praise the French Revolution for such things as religious tolerance, an end to torture in the judicial system, and an end to serfdom. However serfdom had died out centuries before in France (the Revolutionaries were mostly city people - they knew little of rural France) and was against enlightenment opinion long before the French Revolution - the end of serfdom in such countries as Prussia may (or may not) have been hastened by the French Revolution. Religious tolerance? King Louis XVI was religiously tolerant - he had already got rid of the laws persecuting non Catholics in France. An end to torture? Again this had already been abolished in France (in fact if not in name - the Revolution BROUGHT IT BACK). And there was a strong movement against it in legal thought in Europe.
