It's not every day that a new nation is born, and even less common that it doesn't come about through bloody warfare. This one came about by accident, but its new citizens aren't looking back.
Vit Jedlicka was a member of the Party of Free Citizens in his native Czech Republic. He started talking about founding a new country as a political stunt. He was never serious about it, until the people around him started to be. After a while, he had little choice but to actually go ahead and do it. That's how the Free Republic of Liberland was born.
