Twelve who Ruled: The Year of the Terror in the French Revolution

I was re-reading a great work on the French revolution (and there are many great works on the French Revolution).  I was re-reading the classic, Twelve Who Ruled: The Year of the Terror in the French Revolution by R.R. Palmer.  Several observations regarding the revolutionary mood in the Arab world.  People can become revolutionaries even if they were not: none of the 12 men who led the Committee of Public Safety were revolutionaries before.  2) It is not uncommon for young people to lead revolutions: of the 12 men of the Committee of Public Safety, only one was over 40 years of age.  3) Some elements of the middle classes can switch to the revolutionary side (although the characteristics of the middle class in 18th century France are not what they are among, say, Egyptian middle class in the 21st century.  All the 12 men were from middle class (or more) backgrounds.  4) There are limits to the control exercised by the revolutionary elite over developments.  5) The resolve of a revolution is protected by the presence of elements (not only Robespierre) who did not have earthly weaknesses.
