Ceremony of Tunggul Wulung began since the downfall of Majapahit Kingdom whilst Islam entered Nusantara. Many of the royal family could not accept the existence of Islam, since they had Hindu. However there was Islamic kingdom in Java, that is Demak ruled by Sultan Trenggono with Wali Sanga as the advisors. Majapahit Kingdom ruled by Prabu Brawijaya was decreasing and those moslems entered Majapahit with Islam religion by having the daughter of Brawijaya with the son of Demak, that is Adipati Terung.

Then began the era of spreading Islam in Majapahit. Many royal family of Majapahit left the kingdom including Ki Ageng Tunggul Wulung. He went from Majapahit with his seven guards, with his wife Raden Ayu Gadhung Mlati, and also Raden Sutejo and Raden Purworejo which could not be seen by anyone. Besides the travel of Ki Ageng Tunggul Wulung was also followed by abdi dalem kinasih, Nyai Dakiyah.

The travel of Ki Ageng Tunggul Wulung to the West arrived at Beji Hamlet (Diro) where he made "pesanggrahan" (a small palace) which can be recognize today with the heritage of statue pepethan lembu Andhini and sapi Gumarang. On one Friday night (Jumat Pon), Ki Ageng Tunggul Wulung asked for guidance to the Almighty under the tree of Timoho near the river bank of Progo. Ki Ageng Tunggul Wulung with his wife and his seven guards and Nyai Dakiyah were finally mokswa (the body is gone to spiritual world), also with his pets: perkutut, gemak, macan gembong, macan kumbang, macan putih, nogo ijo, nogo ireng, and jago "wiring kuning".

There is a tomb on the place of mokswa Ki Ageng Tunggul Wulung, and it is believed as a sacred and magical place (wingit), then many people often visit the "tomb" for particular reason.

Tradition of tayuban begins when a ledhek (female dancer) who was searching for prosperity in order to get a lot of money when she dances. Then she made a "tirakat" (festing) inside the area of Ki Ageng Tunggul Wulung's tomb, however she was then misteriously dissapeared. Local people believes that she is taken by Ki Ageng Tunggul Wulung.

During the following years in every ceremony of Tunggul Wulung, there is also kenduri (praying together) at the area of the tomb and at the house of Juru Kunci which is then continued by tayuban with gendhing "Sekar Gadhung" and the ledhek would dance without any ibing (dancer's mate), since people believes that the mate would be Ki Ageng Tunggul Wulung himself.
