Susuhunan, or in short version Sunan, is a title used by the monarchs of Mataram and then by the hereditary rulers of Surakarta, Indonesia.
The full title of the Susuhunan in Javanese is: Sampeyan Dalem ingkang Sinuhun Kanjeng Susuhunan Prabhu Sri Paku Buwana Senapati ing Alaga Ngabdulrahman Sayidin Panatagama ("His Exalted Majesty, The Susuhunan, King Paku Buwana, Commander-in-chief in war, Servant of the Most Gracious, Caliph who safeguards the Religion"). This long title is occasionally abbreviated in media with Latin texts as SISKS, denoting Sampeyan dalem Ingkang Sinuhun Kanjeng Susuhunan, followed by the regnal name.
The rulers of Surakarta traditionally adopt the regnal name Pakubuwono (also spelled Pakubuwana Javanese pronunciation: [pakubuwɔnɔ]). Susuhunan is specific to the rulers of Surakarta; the rulers of Yogyakarta, who are also descended from the Mataram dynasty, have the title Sultan.Pakubuwono II, 1727 — 1749 (Kartasura and Surakarta)
