Who is Nyi Roro Kidul, the Queen of the Southern Sea?

The goddess-queen of the Indian Ocean off Java's south coast, bound to the Mataram kings, and to the colour no one wears on her beaches.

The answer

Nyi Roro Kidul, also called Kanjeng Ratu Kidul, is the goddess-queen of the Southern Sea in Javanese legend: the ruler of the Indian Ocean off the south coast of Java, known as the Laut Selatan or Segara Kidul. Her story is bound to the Mataram royal line, whose kings are said to hold a mystical bond with her, and to the beaches of Java's south, where visitors are warned not to wear green, her colour, lest she claim them for her realm. The royal courts of Yogyakarta and Surakarta still hold Labuhan ceremonies of offering to her. Some tellings treat Kanjeng Ratu Kidul and Nyi Roro Kidul as one figure and others as two, and accounts vary.

Who Nyi Roro Kidul is

Nyi Roro Kidul, also honoured as Kanjeng Ratu Kidul, is one of the central figures of Javanese legend: the goddess and queen of the Southern Sea. Her domain is the Indian Ocean that stretches south from Java's coast (the Laut Selatan or, in Javanese, Segara Kidul, the Southern Sea) and she is understood as its ruler, a spirit-sovereign of immense power instead of a mere ghost or local spirit.

Her legend is old and layered, tied to the courts and chronicles of Java, and she stands among the most widely known and most seriously regarded figures in the island's folk and courtly tradition alike. She isn't confined to campfire stories: she has a place in royal ritual, in coastal custom, and in the imagination of millions along Java's southern shore.

The bond with the Mataram kings

What sets Nyi Roro Kidul apart from an ordinary sea-spirit is her place in Java's royal story. She is bound in legend to the Mataram line (the dynasty behind the courts of central Java) through a mystical relationship in which the queen of the Southern Sea is said to be a spiritual consort and protector of the reigning king.

In the telling, the bond is renewed with each ruler, joining the earthly throne of Mataram to the unseen throne of the sea. This is why she belongs as much to statecraft and court ritual as to popular belief: her legend helped express and legitimise the sacred authority of Java's kings, and her name is spoken with the respect owed to royalty. Accounts of the origin and terms of the bond vary between chronicles and tellings.

Don't wear green on the south coast. I don't believe in the Queen, and I'd still follow the rule.

The colour green and the southern beaches

For most visitors to Java's south coast, Nyi Roro Kidul is met first as a warning. The strongest and most widely kept is about the colour green (*hijau*) held to be the queen's own colour.

Don't wear green. At southern beaches such as Parangtritis, near Yogyakarta, and Pelabuhan Ratu in West Java, visitors are widely warned not to wear green, lest the queen take a liking to the wearer and draw them into the sea.
The dangerous coast. Java's south faces the open Indian Ocean, with powerful currents and undertows; the warnings and the real drownings that gave rise to them are woven tightly together in the telling.
A room kept for the queen. Some hotels along the southern coast are said to keep a room set aside for Nyi Roro Kidul, often furnished in green, which guests aren't given.

Whether taken literally or as a mark of respect for a treacherous sea, these customs keep the queen present in daily life along the coast. They're observed by locals and visitors alike, and honoured more often than they're argued with.

The Labuhan offerings

The queen's place in royal tradition is kept alive through Labuhan: ceremonies of offering in which the courts send gifts to her realm. The kratons, or royal courts, of Yogyakarta and Surakarta hold these rites, in which offerings are carried to the Southern Sea and given to its waters in honour of Kanjeng Ratu Kidul and to renew the bond between throne and sea.

Labuhan is a public expression of a private-seeming legend: it takes the mystical relationship between king and queen and enacts it as court ritual, on the shore, before witnesses. The particular offerings, timing and observances belong to court tradition and vary between the two kratons and over time.

How the queen came to the sea

The origin most often told in West Java is Sundanese. A princess of the kingdom of Pajajaran, named Dewi Kadita in the usual version, is cursed by a jealous rival with a disease that covers her skin. Driven from the palace, she wanders to the south coast, hears a voice from the waves promising that the sea will heal her, and walks into it. The disease lifts, and she does not come back. She rules the Southern Sea from that day, beautiful and terrible, and she is the queen the beaches warn you about.

The Central Javanese story begins with a king instead of a princess. Senopati, founder of the Mataram dynasty in the late sixteenth century, meditates on the beach at Parangkusumo, near Parangtritis. The queen rises from the sea, is drawn to him, and takes him to her palace beneath the waves, where they agree the bond that his successors renew. Two stories, two coasts, one queen. Which you hear depends on where you are standing.

Room 308

The Samudra Beach Hotel at Pelabuhan Ratu was built under President Sukarno in the 1960s, and it keeps a room for the queen. Room 308 is furnished in green, with her portrait on the wall and offerings on a table, and it is not let to guests. People come to leave flowers and to ask for things, and hotel staff open it for them. Sukarno himself was said to have consulted her there.

It is the most visited single site of the belief, and it is a hotel room. That is not a diminishment. A tradition that can occupy a modern building without embarrassment is a tradition still in use, and the green curtains are an act of respect from a state hotel to a figure the state's founder took seriously.

The dance with the tenth dancer

The court of Surakarta keeps a sacred dance, the Bedhaya Ketawang, performed once a year on the anniversary of the sunan's accession by nine women dancers in a slow, near-hypnotic form. Tradition holds that the dance was composed with the Queen of the Southern Sea herself, that she attends each performance, and that on some occasions a tenth dancer is seen whom nobody in the court recruited. The dancers fast and observe ritual purity beforehand, and the piece is not performed for tourists.

It is the queen's most refined presence: not a warning on a beach or a room in a hotel, but a work of art that a royal house has kept for centuries as a form of contact with her.

Reading the legend

The sea is dangerous. Java's south coast faces the open Indian Ocean, with rip currents that drown swimmers every year. A queen who takes the unwary in green is a warning that keeps people out of the water more reliably than a sign does.
The kings needed her. A dynasty that claimed a spiritual marriage with the sea's ruler claimed the south coast, and the sea, as part of its realm. The Labuhan offerings still say so.
She is not a ghost. In the tradition's own terms she is a sovereign, and the register in which people speak of her is the one used for royalty, so locals will correct a visitor who calls her a spirit.
The green rule is cheap to keep. Wear another colour, and you have honoured a coast's oldest safety custom and a queen's oldest courtesy at once.

Queen or deputy? One figure or two

There is a genuine complication to name fairly. In some Javanese traditions Kanjeng Ratu Kidul and Nyi Roro Kidul are two names for one and the same queen of the Southern Sea. In others they're distinguished: Kanjeng Ratu Kidul is the supreme queen, and Nyi Roro Kidul is a separate figure, a deputy, attendant or manifestation who serves her, sometimes cast as a princess bound to the sea and its ruler.

Which reading you meet depends on the source, the court and the teller, and neither is the single correct one. It is more faithful to the tradition to hold both than to flatten it, so on the point of who exactly Nyi Roro Kidul is beside Kanjeng Ratu Kidul, accounts vary.

Her legend is within the larger world of Javanese belief, alongside the folk-Islamic and Kejawen strands that also give us the primbon almanac and Java's many ghost figures, such as the kuntilanak. She is the grandest of them, less a spirit to be feared at a crossroads than a sovereign to be honoured at the shore.
