Despite of all the achievements, the French Revolution gradually failed. The Third Estate, which was named the National Assembly, tried to protect the ideas of revolution and to save own power by pursuing people, who criticized the revolt, sentencing them to prisons and to death. This led to mistrust and disappointment of the lower class. So, to me I don't think the French Revolution was a success.
New traditions we're implemented as a result of Enlightenment and new economy based on capitalisma and personal possession rather than hereditary. Although it wasn't immediately, the government did change eventually due to a monarchy. The greatest success of the Revolution for France as well as the whole world was the adoption of the Declaration of the Rights of Man and of the Citizen. A very sensational charter to the contemporary world politics, it combined with the ominous warning from the National Assembly of its pledge “of spreading the ideal of equality and brotherhood” everywhere it established its rule, in provoking reactions of appreciation at first and then fear from the continental monarchs, and that cleared the path of the Revolutionary Wars.
I think the Reign of Terror was a failure. The Reign of Terror was a failure because it only exposed bad people or traitors to the people. Robespierre’s objective was to execute those whom he felt was a threat to him. Though it ended due to Robespierre being sent to the guillotine himself.
Robespierre created the Reign of Terror just to hold his power. Rather than practicing the democratic ideals of liberty and equality that he spoke about in public to the people, he executed traitors.
The French Revolution impacted other countries in various ways. In Europe, the revolution led to a series of wars between various countries and the French. It also led to the rise of Napoleon and the empire he won.
The French Revolution caused the US a great deal of trouble. First, it helped split the country between pro-British and pro-French factions. Second, it led to many problems in foreign policy. The French and British went to war, and the US was caught in between with both countries preying on US shipping to the other country. This eventually led to near-war with the French and finally to the War of 1812 with the British.
