Chain of Revolutions

It is really interesting how the French Revolution inspired a bunch of other revolutions right after it, which is similar to what happened during the Arab Spring a few years ago.  The Haitians took advantage of the weakness of Franc after their revolution to try their own one.  Also, the Haitians apparently did not learn anything from the French Revolution, because theirs was also bloody and violent, although violence might have been necessary at that point in time for anyone to take them seriously.  Greece also had a successful revolution against the Ottomans, which led to other European nations wondering if their government systems would ever be safe, since the people could just overthrow it and place someone else in charge if they were unhappy.
