Once upon a time HRE was walking down he road. A gust of wind blew off his hat, but he had a bunch of wars to fight so he didn't notice.

The hat sat there. And sat there. And got rained on. And sat there.

Until one day tiny tendrils of hat material crawled into the ground and took root. For many years the hat was left incubating, but one morning, like a chicken bursting from an egg, Germany exploded out of the hat. Covered in yolk. Yolk that smelled like beer.

And thus Germany was born!
