Villarvattom
Villarvattom was the putative Christian dynasty in Kerala. It ostensibly existed until the middle of 15th century AD. Thoma of Villarvattom was apparently one of its last kings.
Saint Thomas Christians (also known as Syriac Christians) is a prosperous and politically powerful religious community in Kerala. They claim high-caste status by claiming to be descendants of Brahmans (Namboothiris) that converted to Christianity in 52 AD. Sreekumar & Eldhose (2024) suggest that the story of Villarvattom is an "invented and imagined tradition necessitated and facilitated by the unique socio-political structures" the Christians were participating in.
