Answer:
Its importance
The rule of law is very important for a democracy because it is in itself a democratic concept: the idea that all individuals are subject to the law, including rulers, creators of the law, and judges.
Without the rule of law, it is very hard for a democracy to flourish because its absence often implies that some people are above the law, or have more legal rights than others, a situation that would damage democracy.
Its benefits
The main benefit of the rule of law is that it gives every individual the same legal rights as everyone else. This equality before the law results in a more just society, and also results in a more developed and wealthier society, because equality before the law and property rights enforcement have been shown in many studies to correlate strongly with economic growth.

Before the Renaissance, during the Middle Ages, people relied solely on the Catholic church for their information about the world. They based their facts on the Bible and what religious figures told them. During the Renaissance, a more secular way of thinking developed. As the printing press grew, more people became literate and were able to interpret the Bible for themselves. This led to the creation of new religions and theories about science. People began to challenge the old social order and authorities and began to question the morals and motives of the seemingly corrupt Catholic church.
