Annwvyn

Annwvyn is a kingdom ruled by Arawn, distinct from Pwyll’s Dyved and governed through a royal court, household, and body of nobles. Its political order becomes the setting for a year-long exchange of identities: Pwyll rules there in Arawn’s likeness while Arawn takes his place in Dyved. The arrangement turns an encounter prompted by a breach of hunting courtesy into a struggle over the kingship of Annwvyn, and ultimately places both of its kingdoms under one ruler.

Realm and Rival Kings

Arawn introduces himself as a crowned king from Annwvyn after confronting Pwyll for driving away Arawn’s hounds and setting his own dogs upon the stag they had brought down. He treats the act as a serious discourtesy, but offers Pwyll a way to regain his friendship: defeat Havgan, a king whose dominions lie opposite Arawn’s and who is continually at war with him. The conflict is thus presented not as a distant dispute but as a contest between rival rulers over neighboring domains within Annwvyn.

The terms of Arawn’s proposal establish how access to the realm will work. He will send Pwyll there in his own form and likeness, provide him with a lady as companion, and ensure that the members of the court cannot recognize the substitution. Pwyll is to rule in Annwvyn for a year, while Arawn governs Dyved in his place; at the end of the year they will meet again at Glyn Cuch. Arawn also guides Pwyll to the palace and its dwellings, where Pwyll can observe the court’s customs before taking up the kingship.

Pwyll’s Rule and the Contest with Havgan

At the appointed meeting, Pwyll faces Havgan in Arawn’s likeness. His first blow splits the boss of Havgan’s shield, breaks his armour, and throws him from his horse with a deadly wound. Havgan asks Pwyll to finish what he has begun, but Pwyll refuses to strike again. That refusal is decisive: Arawn had warned him that a second blow would allow Havgan to fight again the next day as strongly as before. The contest therefore turns on restraint as well as force; Pwyll wins by obeying the particular limit that Arawn has disclosed.

After Havgan is carried away, Annwvyn’s nobles ask who should be their king. They acknowledge Pwyll’s claim over the whole realm, and he receives their homage. He declares that those who come humbly should be received graciously, while those who refuse obedience will be compelled by force of swords. By the following noon, both kingdoms are in his power. Annwvyn’s unification is thus shown through the submission of its nobles and the rapid extension of Pwyll’s authority, rather than through a further description of battle.

Exchange, Return, and Other Connections

Pwyll keeps the agreement and meets Arawn at Glyn Cuch. Arawn thanks him for his friendship and tells him that he will see what has been done for him in his own dominions. They exchange their proper forms again: Arawn returns to his court and household, whose members had not noticed his absence, while Pwyll returns as prince of Dyved. The episode makes Annwvyn a place where kingship can be exercised through a borrowed identity, but the exchange remains bounded by a fixed term, a promised meeting, and the obligation to respect the one-blow rule.

Annwvyn also appears as the provenance of the swine sent to Pryderi. Gwydion tells Math that the unfamiliar animals belong to Pryderi, son of Pwyll, and were sent to him from Annwvyn by Arawn. This connection extends the realm’s reach beyond the royal contest: its gifts enter the affairs of another kingdom and become objects of political interest. Together, the exchange of kings and the transfer of the swine associate Annwvyn with both sovereign power and consequential dealings across realms.
