Sjair Abdoel Moeloek (Perfected Spelling: Syair Abdul Muluk) is an 1847 syair (poem) credited variously to Raja Ali Haji or his sister Saleha. It tells of a woman who passes as a man to free her husband from the Sultan of Hindustan, who had captured him in an assault on their kingdom. The book, with its theme of gender disguise common to contemporary Javanese and Malay literature, has been read as repositioning the hierarchy of men and women as well as the nobility and servants.
