Stop picking nits. If I got the year wrong, the concept remains. The French Revolution that ended with Napolean taking power was Leftist.
No. The French Revolution was a revolt against a leftist king, King Louise XVI and his tax and financial policies.
It actually did result in the 1st Republic. This brief moment in the history of France actually had a constitution.
Unfortunately, Napoleon seized power in 1804 and became emperor and that constitution was discarded. His wars across Europe was entirely funded by stealing everything from his enemies, and also was used to fund the empire itself. They lasted until Napoleon overextended his resources and the rest of Europe started to form an alliance against him. He lost in Russia, resulting in his being deposed as emperor in 1814. He was still the general of the armee however, and continue his wars. He was finally defeated for good in Belgium at the hands of the Prussian army (one of the allies), at the Battle of Waterloo.
Despite all this, some good things came out of it:
* The widespread adoption of preserving food by sterilization in bottles (and later cans).
* Getting rid of useless doctors and putting surgeons in charge (then not considered real doctors!), and the concept of the ambulance. With so much raw material to practice on (wounded soldiers), medicine was bound to improve! No more fancy chat. It was the wound they were after to treat, never mind your status in life, or making up lists of 'symptoms' like Nostalgia.
* The sale of the Louisiana Territory to the United States, effectively doubling the size of the United States at the time.
* Improving the overall education system in France, even if it was by use of public (government funded) schools that were funded by the wars.
