Duckistan was discovered around 100AD (Anno Duck), by a group of duckist explorers, lead by the very founder of the religon himself, Donald Duck. Before then the duck shaped piece of land had remained unpopulated. Maybe the locals were unfriendly or the food was bad or something. But anyway, Donald Duck, lead by the explorers founded Duckistan, and began setting up towns and villages, including the current capital, Ducksberg. It was here that he announced that the religion of duckism had become official, and Ducksberg has never been stronger.
