The line of succession to the former throne of Travancore, a major Indian salute state, is notable for utilising a combination of matrilinealagnatic seniority and matrilineal agnatic primogeniture. The heir apparent is styled "Maharajkumar Sri (name) (personal name), Elaya Raja of Travancore." The monarchy was abolished in 1949, when the state fully acceded to India.
The royal family utilises an ancient Nair principle of matrilineal succession, known as Marumakkathayam, which proceeds as follows:
The younger brothers and cousins of the Maharajah, based on seniority of age; a cousin may succeed before a uterine brother if older.
The nephews of the Maharaja through his sisters, in order of age; a younger sister's son may succeed before an elder's if that son is older.
As per the above principle of succession, the sons of a Maharaja or of those in the line of succession cannot succeed to the throne, nor, if those children bear sons, can those sons be in the line of succession. If the matriline fails, as happened in 1798 and 1924, daughters from another matriline can be adopted to continue the succession.
