The Enlightenment was a sprawling intellectual, philosophical, cultural, and social movement that spread through England, France, Germany, and other parts of Europe during the 1700s. Enabled by the Scientific Revolution, which had begun as early as 1500, the Enlightenment represented about as big of a departure as possible from the Middle Ages—the period in European history lasting from roughly the fifth century to the fifteenth.
The millennium of the Middle Ages had been marked by unwavering religious devotion and unfathomable cruelty. Rarely before or after did the Church have as much power as it did during those thousand years. With the Holy Roman Empire as a foundation, missions such as the Crusades and Inquisition were conducted in part to find and persecute heretics, often with torture and death. Although standard at the time, such harsh injustices would eventually offend and scare Europeans into change. Science, though encouraged in the late Middle Ages as a form of piety and appreciation of God’s creation, was frequently regarded as heresy, and those who tried to explain miracles and other matters of faith faced harsh punishment. Society was highly hierarchical, with serfdom a widespread practice. There were no mandates regarding personal liberties or rights, and many Europeans feared religion—either at the hands of an unmerciful God or at the hands of the sometimes brutal Church itself.
The Scientific Revolution and the Enlightenment, however, opened a path for independent thought, and the fields of mathematics, astronomy, physics, politics, economics, philosophy, and medicine were drastically updated and expanded. The amount of new knowledge that emerged was staggering. Just as important was the enthusiasm with which people approached the Enlightenment: intellectual salons popped up in France, philosophical discussions were held, and the increasingly literate population read books and passed them around feverishly. The Enlightenment and all of the new knowledge thus permeated nearly every facet of civilized life. Not everyone participated, as many uneducated, rural citizens were unable to share in the Enlightenment during its course. But even their time would come, as the Enlightenment also prompted the beginning of the Industrial Revolution, which provided rural dwellers with jobs and new cities in which to live.
Whether considered from an intellectual, political, or social standpoint, the advancements of the Enlightenment transformed the Western world into an intelligent and self-aware civilization. Moreover, it directly inspired the creation of the world’s first great democracy, the United States of America. The new freedoms and ideas sometimes led to abuses—in particular, the descent of the French Revolution from a positive, productive coup into tyranny and bedlam. In response to the violence of the French Revolution, some Europeans began to blame the Enlightenment’s attacks on tradition and breakdown of norms for inducing the anarchy.
Indeed, it took time for people to overcome this opinion and appreciate the Enlightenment’s beneficial effect on their daily lives. But concrete, productive changes did, in fact, appear, under guises as varied as the ideas that inspired them. The effects of Enlightenment thought soon permeated both European and American life, from improved women’s rights to more efficient steam engines, from fairer judicial systems to increased educational opportunities, from revolutionary economic theories to a rich array of literature and music.
These ideas, works, and principles of the Enlightenment would continue to affect Europe and the rest of the Western world for decades and even centuries to come. Nearly every theory or fact that is held in modern science has a foundation in the Enlightenment; in fact, many remain just as they were established. Yet it is not simply the knowledge attained during the Enlightenment that makes the era so pivotal—it’s also the era’s groundbreaking and tenacious new approaches to investigation, reasoning, and problem solving that make it so important. Never before had people been so vocal about making a difference in the world; although some may have been persecuted for their new ideas, it nevertheless became indisputable that thought had the power to incite real change. Just like calculus or free trade, the very concept of freedom of expression had to come from somewhere, and it too had firm roots in the Enlightenment.
