In the state of Kerala, India, the Nambudiri Brahmin caste traditionally practiced henogamy, in which only the eldest son in each family was permitted to marry. The younger children could have "sambandha" (temporary relationship) with Kshatriya or Nair women. This is no longer practiced, and in general the Nambudiri Brahmin men marry only from the Nambudiri caste and Nair women prefer to be married to Nair men. Tibetan fraternal polyandry (see Polyandry in Tibet) follows a similar pattern, in which multiple sons in a family all marry the same wife, so the family property is preserved; leftover daughters either become celibate Buddhist nuns or independent households. It was formerly practiced in Tibet and nearby Himalayan areas, and while it was discouraged by the Chinese after their conquest of the region, it is becoming more common again.
