Born in the small town of Isafjörður, Hannes Hafsteinn was the fattest king in the history of Iceland. He was so fat that the Imperial Palace had to be reinforced so as to not crumble under his enormous layers of fat.

Hannes was not always fat though, in his younger years he was actually quiet fit. However, he discovered that he was gay around the time he graduated from carpentry school. He soon met and became the lover of an older man (King consort Halldór) fifty years his senior. Halldór had a fat fetish and force feed Hannes in order to fatten him and fulfill his sexual fantasies.

In only two short years Hannes got so fat that he couldn't walk any more or move his arms. Impressed by his stupidity (a trait that has always been revered amongst Icelanders) the people of Iceland made him their king.
