Today I learned that the King of Sweden, Karl XVI, was only the tenth King of Sweden, Karl.
The first six charles were invented by the young man in the picture, Johannes Magnus, who decided to glorify Sweden by inventing thousands of years of imaginary history, including no less than 143 kings (more or less imaginary), beginning in 2259 BC.
The Swedes decided to flow with him, and until the numbering day of the kings of Sweden is based on imaginary history.
