In 1831 Thomas Macaulay addressed the House Of Commons:
"All history is full of revolution, produced by causes similar to those which are now operating in England. A portion of the community which had been of no account expands and becomes strong. It demands a place in the system, suited not to it former weakness, but to its present power. If this is granted, all is well. If this is refused, then comes the struggle between the young energy of one class, and the ancient privileges of another".
He warned of past examples: in Rome, the plebians' clash with the patricians, which led to civil war, the fall of the Republic, and the rise of the Caesars: in America the colonists' war to cast off British rule: and in France, the repressed Third Estate's overthrow of the monarchy. From this history Macaulay drew the inescapable lesson: " Reform, that you may preserve".(1)
Zakaria finds similarities in past revolutions with the Progressive party movement in the United States now.
