Most people use the words king and emperor interchangeably. While they may both stand for a position of power there are some differences between a king and an emperor that most people do not know.
The king of a country or land can rise to power if they have conquered the land or if they have been born into royalty.
Members of the royal family will pass this position down. One day the price of the country will become the king. The Emperor of the land usually got into power because they conquered the land.
In the land that the emperor occupies they are the highest power. There is no one greater than they are and their say is usually final. The king may not hold a position of absolute power.
There may be another governing body that makes and oversees the law. For example, while England has a King it is the Prime Minister that is responsible for the government operations.
The title of emperor often has to do with religion. The religion of the emperor is often the official religion of the area and people are expected to practice and follow it.
The king often does not have anything to do with religion. They are not the head of the religion and most people are free to practice as they please. Emperors may be considered to be God-like figures in their land and the king is not.
In modern times there are only a few kings and emperors left in the world. England is a country that is notable for its royal family. Japan is one of the few countries in modern times that is led by an emperor.
One of the biggest differences between an emperor and the king is some of the responsibilities that they once had. Emperors have some of the highest responsibilities of those in the land.
They had in charge of all of the economic affairs and the military in the land that they were in charge of. The emperor had complete control over the military. They can declare war and conquer new land. They were responsible for the development of any of the land they acquired.
They may have been in control of several nations at the same time and most emperors were looking to grow and expand. The king still had a very powerful position but they had some other areas where they had most of their responsibility.
The king had to watch over the well-being of the kingdom and the people that he ruled over. He had to deal with trading and financial matters.
While modern times do not put as much importance as a king or an emperor at one time they were the most desired positions within a country and they both come with respect.
There are some differences between a king and an emperor. The emperor had complete power and while the king did hold a lot of power the emperor still had a higher position of power than a king.
