The Kings of Laos could marry a various amount of wives (King Sisavang Vong married 15) and only women of royal birth could have the title " Samdach Brhat Rajini Ekka Akkhara Maha Sri", if the king had more than one wife. If she was a commoner, her title was "Mom". When there was a Vice-King, they would be styled as the "Uparaja", but since 1959, on the death of Prince Phetsarath Rattanavongsa, the position was abolished.
