, from its beginnings in 1789 until the fall of Napoleon in 1815. On the social and political front, Carnot was the author of many reforms that he thought to be for the good of the Republic. One of these was the proposal for compulsory public education for all citizens. He also penned a proposal for the new Constitution which included the “Declaration of the Duties of the Citizens” that held that there should be not only education but military service for all citizens of France between the ages of twenty and twenty-five. These proposals were in accordance with the Revolutionaries' thinking at the time, which held that men and women should be honored through ability and intelligence rather than through birthright, even though Carnot himself was nobly born. This style of thinking may well have been instrumental in Napoleon Bonaparte's rise to power as it was Carnot who promoted him from Captain to General.

But perhaps his greatest achievements, in deference to the French Revolution itself, were those of a military nature. If not for Carnot, the modern waging of war with mass armies and strategic planning would not exist. As a military engineer, Carnot favored fortresses and defensive strategies, but with the constant invasions decided to take his strategic planning to an offensive strike. From his intellect sprang the maneuvers and organization that turned the tides of war from 1793 to 1794. The basic idea was to have a massive army separated into several units that could move more quickly than the enemy and attack from the flanks rather than head on, which would lead to slaughter and defeat. It was his initiative to train the conscripts in the art of war and to place new recruits with experienced soldiers rather than having a massive volunteer army without any real idea of how to wage battle. He also created a new political strategy based on disrupting communication between enemy nations of England and Austria while concentrating attack effort on England. Carnot’s military influence and authority were eventually used to bring about the downfall of Robespierre.
