The Nambudiri, also transliterated as Nampoothiri, Nambūdiri, Namboodiri, Namboothiri and Nampūtiri, are a Malayali Brahmin caste, native to what is now the state of Kerala, India, where they constituted part of the traditional feudal elite. Headed by the Azhvanchery Thamprakkal Samrāṭ, the Nambudiris were the highest ranking caste in Kerala. They owned a large portion of the land in the region of Malabar, and together with the Nair monarchs, the Nambudiris formed the landed aristocracy known as the Jenmimar, until the Kerala Land Reforms starting in 1957. Naturalized Tulu Brahmins who took up Nambudiri customary ways are known as Embranthiri Brahmins.
