Countryballs began as Polandball, an online comic format that turned countries into round, flag-coloured characters with simple faces and exaggerated national stereotypes. The format spread from forums to YouTube, TikTok and social media, where creators made short animations, songs and skits about history, politics and everyday rivalries. This kind of fan-made song captures that spirit in miniature, using a catchy tune to signal a Countryballs world before a single joke is told. It remains popular because the characters are instantly recognisable and the humour travels easily across languages.
