what was the one significant development in 20th century according to French Revolution​

Answer 1

Answer:

The French Revolution And The Emergence Of Modern Strategies

The eruption of the French Revolution in 1789 delivered a blow to the emerging rationalistic conception of strategy from which it never quite recovered, though some of its precepts were echoed by later schools of thought, such as those of Jomini in his great work The Art of War (1838) and the systems analysts of the 1960s and afterward. The techniques of the armies of France under the Revolutionary government and later the Directory (1795–99) and Napoleon (1799–1814/15) were, superficially, those of the ancien régime: drill manuals and artillery technique drew heavily on concepts outlined in the days of Louis XVI, the last pre-Revolutionary French king. But the energy unleashed by revolutionary passion, the resources unlocked by mass conscription and a powerful state, and the fervour that followed from ideological zeal transformed strategy.
