Caused radical changes in France
The battle of Waterloo's greatest notable success was its ability to drastically alter French attitudes. This change is assessed as one of the best significance of the battle of French revolution.
Prior to this conflict, the French populace supported Napoleon's aspirations to rule all of Europe and his quest for "La Gloire" wholeheartedly.
France was the adversary of the alliance of European Armies during the conflict. The other countries all agreed that France should make good on their losses. The entire French territory was removed from France and was to be returned to its old boundary, as it had been in 1790.
The struggle was lost, but on the plus side, France had succeeded in forging national unity. It made it simpler for Louis to enact changes and set up a reliable government for the nation.
