The Kingdom of Cardolan was founded in 861 of the third age by Cardolan, the prince of Arnor. Later Hobbits settled in the Cardolan kingdom. And so Cardolan has become a place where hobbits and people live together. But after the witch king Angmar reached the peak of his power, he attacked Cardolan. And it has invaded many Orc Cardolan. Humans and hobbits managed to resist the Orcs for a while. But then a major plague outbreak began in Cardolan. And the people of Cardolan have become weaker. Cardolan was completely demolished in 1409 of the third age. However, after many years, Aragorn rebuilt Cardolan's buildings and enabled people to live in Cardolan.
