The House of Sisowath (Khmer: រាជវង្សស៊ីសុវត្ថិ, UNGEGN: Réachôvôngs Sisŏvôtthĕ, ALA-LC: Rājavangs S″īsuvatthi[riəceaʔʋɔŋsiːsoʋat]; lit.'Sisowath dynasty') is one of the two royal houses of Cambodia, alongside its counterpart, the House of Norodom. Both it and its sister house have a claim to the throne as descendants of King Ang Duong. Its members are the descendants of King Sisowath who reigned from 1904 to 1927. It was the ruling royal house from 1904 to 1941. It has produced three monarchs of Cambodia, and five prime ministers.
^ abAfter the death of King Norodom Suramarit, his consort Queen Sisowath Kossamak served as monarch for ceremonial purposes only (as a "symbol, incarnation, and representative" of the dynasty), while the powers of head of state were delegated to her son Norodom Sihanouk, who was appointed "Chief of State" whose powers equal that of a monarch.[1][2]

After a series of maneuvers, Sihanouk had himself named Cambodia's chief of state with his mother, Queen Kossamak, continuing to serve as a monarch for ceremonial purposes.
