Who said the king of world?

The phrase "King of the World" isn't typically attributed to a specific person or historical figure. It's more of a common phrase used in different contexts, often with different meanings.

Here are some possibilities:

* Figurative Speech: The phrase is sometimes used metaphorically to describe someone who has achieved great power, influence, or success. For example, someone might call a successful entrepreneur the "King of the World" in their field.

* Popular Culture: The phrase has been used in movies and TV shows. For example, in the film "Titanic," Jack Dawson (Leonardo DiCaprio) famously shouts "I'm the king of the world!" while standing on the bow of the ship.

* Religious Contexts: Some religious texts may refer to a divine figure as the "King of the World," depending on the specific belief system.

If you have more context, such as a specific situation or a quote, it might be easier to determine who might have said it and in what sense.
