'Historians say that many families, including those from Kerala, migrated to Sri Lanka to escape to escape Muslim rule in south India. I think that Sri Rahula probably came from one of these families. He is said to have come from the Skandavara family (Kandavuru kula) which is of Kerala origin. He was influential in the royal court of his time. The families of Sena Lankadhikara and Alagakkonara belong to the Kerala families that had migrated to Sri Lanka to escape Muslim rule.
Sena Lankadhikara’s descendants retained their Malayalam names and titles. The Alagakkonaras, who were a rich Kerala trading family, changed their name to the Sanskrit ‘Alkesvara’. Paranavitana says both families married into the royal family. He says that Sena Lankadhikara was married to a sister of Buvaneka bahu IV and that Vickramabahu III (1359-1374) was his son. Alakesvara and his two brothers were joint husbands of Jayasiri, the sister of Vikramabahu III and mother of Buvaneka bahu V (1374-1408).
These two families monopolized the position of chief minister for decades. Sena Lankadhikara was Chief Minister to Buvaneka bahu IV (1341-1351) and Parakrama bahu V (1351-1359). The position was similar to the modern ‘Prime Minster’ and carried the designation ‘Lankadhikara’. It carried much power. The Alakesvaras thereafter displaced Sena, and held on to the position for half a century.
Nephew Virabahu and son Kumara Alakesvara succeeded to the position thereafter. Paranavitana says Kumara was probably the son of Queen Jayasiri, and therefore brother of the reigning king. Then Vira Alakesvara took over the position. When Vira Alakesvara was taken prisoner to China the grandson of Sena stepped into the post'.
