The population of the colonies that later became the United States increased steadily in the decades prior to , and including, the American revolution. The first decennial census took place in 1790 . Since that time, the natural increase, i.e, the excess of births over deaths, has been a constant contributor to popular growth. The other factor, immigration, has ranged for negligible to large at various points in the nation's history.
After 1830, immigration began to grow again. Although the birth rate showed a decline , the net population growth rate remained high until after the Civil War. In the decade ending 1870, population growth dropped below 30% for the first time in the nation's history. Substantial immigration kept the population rising at 20% or more for each decade until 1920, when the effect of Word War I reduced it to 14.9% .
C.Northern capitalists and industrialists came to dominate on the national scene, taking power away from the former southern slaveholder.
The struggle for power among the revolutionary factions like Cordeliers and Girodins caused the French Revolution to slip back from its original ideas and move towards authoritarian regime. These groups in order to gain power and establish their respective ideologies killed and persecuted thousands of people. They carried some outlandish policies like reorganizing Calendar and establishing a church called Cult of Reason. They didn't establish democratic principles and institutions and failed to control and uphold public safety. Later we see Napoleon become the dictator of France and began to fallow expansionist policies. So we see French Revolution was a transition from one authoritarian regime to another authoritarian regime.
