During the 19th century, many changes in the class system occurred over time. Starting with the Victorian class society, the divisions between the upper, middle, and working class were all separated very distinctly. Following the Industrial Revolution, Renaissance, Reformation, as well as the Enlightenment, this structural barrier was destroyed. Philosophers from all classes were accepted and the fight for justice of classes were finally in place. It may have still been harder to create your potential based off your previous class, however, now, your work ethic could determine the fate of your future; not the family you were born in.
Classic liberalism changed throughout the 19th century alongside the changes of the social classes. Human rights and freedoms, creativity for all individuals, and acceptance of all previous class divisions changed throughout history in this timeframe. Liberalism founded these events throughout this entire century, creating justice, and rights for all.
