The Dark Ages

Major events leading to the Age of Reason
European Enlightenment Timeline

Since the collapse of the Western Roman Empire in the fifth century, Europe's mostly illiterate population had been guided by superstition, fear of an angry God and ignorant obedience to authorities who may or may not have their subjects' best interests at heart. Unable to read the scriptures or the law for themselves, their only option was to obey or not obey - and challenging the authority of the king or the church often resulted in a slow and painful death. A thousand years later, that finally began to change.

A series of intellectual and spiritual movements prompted some individuals to suggest that humans had been living in the Dark Ages. A renewed awareness of old knowledge, combined with developments in science, theology and philosophy, helped turn on the lights, so to speak. This movement, spanning the 18th century, is known today as the Enlightenment, or the Age of Reason.

Early modern Europe emerged from the 1500s to about 1750 in response to intellectual and political changes from the Middle Ages and Renaissance. During the Middle Ages, Europe went through a time of crisis; plagues wiped out much of its population, government organization caused strong class divisions, and revolts led to religious and political instability. During this time, European Christianity enforced the divine right of kings, and its superstitious and fearful population was apt to follow religious authority.

In the early 15th century new inventions, like the Gutenberg printing press, allowed for quicker communication and the spread of ideas. Around this time, the Age of Discovery began, as Europeans began exploring areas of the world by sea. This Age established new trade, wealth, and knowledge to spread throughout the country. The Age of Discovery helped Europe transition out of the Middle Ages and into a period known as the Renaissance, which led to the rediscovery and appreciation of ideas associated with Ancient Greece and Ancient Rome. The Renaissance reawakened all aspects of European life that the people had cast aside during the Middle Ages, including art, literature, music, science, and politics. With this movement, Europe rediscovered political systems like the republic and the importance of democracy; these ideas would eventually make their way to American politics.

The English Enlightenment and French Enlightenment influenced many of the ideas that came to the colonies. In the 17th century, England moved from an absolute monarchy to a constitutional monarchy, an uncodified constitution that utilizes a parliament while giving the monarch ceremonial duties or reserve party. This allows governmental institutions to counter the monarch's power and avoid absolute power.

During this time, French Enlightenment ideas were also starting to emerge. Montesquieu pushed the importance of the separation of powers, which helped keep one branch from becoming too powerful. The French Enlightenment differed from the English Enlightenment in that it used a humanistic approach. The French introduced the ideas of individual rights and freedom and the government's duty to protect equal liberty. These movements introduced concepts that greatly influenced the American Enlightenment thinkers and ideas.

With increased trade and communication between the colonies and Europe, the Enlightenment movement reached America in the 18th and 19th centuries. The educated were the first to hear of these ideas, which they then spread to those who could not afford an education.

Benjamin Franklin was one of the most influential American Enlightenment thinkers of this time, and he helped establish the Enlightenment in the United States. Franklin had much experience with the printing press, which he used to print copies and spread Enlightenment ideas. In 1729, he began publishing The Pennsylvania Gazette, a newspaper that focused on society, culture, and politics. The Gazette quickly became the most popular news source in the colonies. In 1733, he published Poor Richard's Almanac, which featured practical proverbs, and became one of the most popular publications in the colonies. Franklin's publications helped circulate Enlightenment ideas and values to the American public.

Republicanism and the American Enlightenment

With the changes of the American Enlightenment, many people struggled to find a way to reestablish their religious beliefs. Classical republicanism emerged as a way to combine the beliefs of reason, religious tolerance, and natural rights. Republicanism moved away from the divine rights practiced in Europe and France; instead, it pushed for a structure of government chosen by its people. This was rooted in the belief that every citizen has God-given rights.

The Enlightenment ideas introduced to the American people helped shape the nation before and after the American Revolution. Leading up to the Revolution, many leaders looked to history to guide their choices in making a strong government. The ideas of freedom, equality, and religious tolerance spread rapidly through the colonies, but the American people did not yet experience them since the colonies were still tied to England. The desire for these virtues helped drive the rebellion against England for the freedom advocated during the Enlightenment.

The Enlightenment and the American Revolution

In many ways, the American Enlightenment contributed to the American Revolution by introducing a democratic society founded on the equal participation of its citizens. The Declaration of Independence is rooted in Enlightenment ideals, specifically those of John Locke, whose writings are reflected in early American doctrine. The Declaration of Independence proclaims that citizens have God-given and inalienable rights, consent, equality, and the right to alter or abolish government.

The American Enlightenment was a time of intellectual and social change that took place in the colonies as a result of the European Enlightenment. During the European Renaissance, knowledge of science, art, music, and literature lost during the Middle Ages reappeared. Increases in literacy led to a Scientific Revolution; people began to use reason and logic to question the divine rights imposed by the Church. John Locke was a predominant figure in the Enlightenment, and his Two Treatises of Government claims that governments exist through the consent of the governed, not through a divine right to rule. This period introduced the Age of Reason or European Enlightenment and put scientific reason at the forefront of thought. With the correlating Age of Discovery, England's trades, economy, and beliefs began to spread throughout the world, especially in the Americas.

The Renaissance, Scientific Revolution and Reformation

First, the Renaissance reawakened knowledge of science, art and culture that had been lost during the Middle Ages and began to shift the focus of these disciplines to humans rather than the divine. Higher rates of literacy then ushered in the Scientific Revolution, and human knowledge increased rapidly, laying the foundation for a scientific, rather than religious, world view.

At the time, it was controversial to explain the natural world in a way that didn't involve any spiritual force. Galileo, for example, was imprisoned for the rest of his life after announcing that the Earth revolves around the Sun, because religious authorities said he was challenging scripture. Galileo was a religious man and didn't intend to undermine the Bible. But gradually, all of this new scientific knowledge did lead a lot of people to question some of the traditional teachings of their churches.

Martin Luther went so far as to say the established church was interpreting the Bible incorrectly. His protest led to the Protestant Reformation and broke the monopoly of power held by the Catholic Church.

The Age of Reason

People began to wonder that if the church had been wrong about the natural world or even the Bible, maybe it could be wrong about other things, too. The Age of Reason gave rise to a completely new way of thinking. Instead of trying to understand how God orchestrated everything in their lives, people started to consider how they might shape the world around them. The result was a new emphasis on scientific discovery and a boom in higher education. Reading someone else's experiment wasn't as good as conducting your own. Accepting what you'd been taught by others wasn't as good as challenging and modifying their assumptions. This was especially true of the relationship between people and the institutions in authority over them.

During the Middle Ages, Europeans were taught that God had orchestrated events to put their monarchs in charge. Who were you to question their divine right? But then England was plagued by political turmoil, and a series of failed governments in the 1600s disrupted the English monarchy, prompting Enlightenment thinkers to consider how their philosophy might apply to government.

Enlightened Ideas of Government

In 1689, an Englishman named John Locke published an anonymous essay titled Two Treatises of Government. In the first treatise, Locke argued that no monarchy had a divine right to exist; kings held power by the luck of their birth. Locke's second treatise, stating that governments should only exist by the consent of the governed, was more influential in America. As you might imagine, Locke's ideas were unpopular with the people who held power in England, and he never acknowledged that he was the author of the Two Treatises.

Other Europeans contributed enlightened ideas of government, as well. The Baron de Montesquieu proposed that society might benefit from a separation of government powers. Jean-Jacques Rousseau went so far as to suggest that society should be ruled by the 'general will' of the people, essentially advocating for direct democracy.

The American Enlightenment

The Enlightenment reached the colonies through the port cities. At first, such philosophy circulated only among the educated elite. Then, Benjamin Franklin, arguably the single most important figure of the Enlightenment in America, printed inexpensive pamphlets and newspapers to spread the ideas quickly. He published Poor Richard's Almanack to entertain the colonists and instill Enlightenment values in them. While Europeans considered, discussed and sifted through these ideas for a century, Americans put them into practice.

Free from the kind of entrenched power that had dominated Europe for centuries, a generation of young American leaders was absolutely willing to question not only the role of the king, but the churches and even God Himself. A theology, known as rational Christianity, emerged. It taught that God gave humans the ability to reason, allowing them to understand and follow moral teachings, regardless of which religious group they belonged to. Religious tolerance became even more widespread.
