Who is first king of Asia?

The title of "first king of all of Asia" is generally regarded as a mythical or legendary title. In ancient Mesopotamian mythology, the first king to rule over the lands of Asia was Sargon of Akkad, who reigned in the 23rd century BC. However, it is important to note that the designation "first king of Asia" is a construct of historiography and is not rooted in any historical evidence or documentation.
