A king is a male monarch who holds a royal title. This title represents a person who leads a nation or a state. In some systems, a king is an absolute monarch. An absolute monarch holds unrestricted governmental power. This person exercises full sovereignty over their nation. In modern times, the title can mean different things.

The word "king" has a very deep linguistic history. It traces back to the late Old English word "cyning." This word meant a ruler or a leader. It comes from the Proto-Germanic root "kuningaz." This same root created similar words in other Germanic languages. For example, Dutch uses "koning" and German uses "König." The exact origin of "kuningaz" is still a mystery to scholars. 
Linguists have two main theories about the meaning of the word. One theory links it to the Old English word "cynn." This word means family or race. This suggests a king was the leader of his kin. Another theory says the term meant someone of noble descent. This would connect kingship to an aristocratic or divine lineage. Historians still debate these social and ideological meanings today.

In the modern world, eighteen kings are recognized today. These men serve as the heads of state for sovereign states. Most of these rulers serve within constitutional monarchies. However, some kings rule through absolute monarchies. The King of Saudi Arabia is one example of an absolute ruler. The King of Eswatini is another example. 

Different countries use various methods to choose their kings. Some kingdoms are hereditary, meaning the title passes through a family. For instance, King Charles III of the United Kingdom is a hereditary monarch. Other systems are elective, where a king is chosen. King Norodom Sihamoni of Cambodia is an elective monarch. Some kingdoms are semi-constitutional, like the one in Morocco. 


Kingship connects to many different fields of study. It relates to anthropology through the study of "big men." It also connects to political science and legal systems. The concept of the "divine right of kings" is a historical idea. Many different cultures have had their own versions of royal titles. These include the titles of raja, khan, or negus. The study of kings helps us understand how societies organize power.
