8. The Carbonari (Italy)
No one knows how or exactly when the Carbonari came into existence. But as speculation goes, it originated around the time when the Congress of Vienna was deciding on what to do with the territories conquered by Napoleon. By 1815, Italy was cut into several pieces. This Italian secret group is said to have had 60,000 members and they rose in revolt against King Ferdinand who was ruling over Sicily and Naples. He soon had to give up his power. This was followed by the whole of Italy rising up into a widespread movement that eventually ended in the unification of Italy in 1861.
