Despite the importance of Buddhism to Lao Loum and some Lao Theung groups, animist beliefs are widespread among all segments of the Lao population. The belief in phi (spirits) forms the relationships of many Lao with nature and community and provides one explanation for illness and disease.
Belief in phi is blended with Buddhism, particularly at the village level, and some monks are respected as having particular abilities to exorcise malevolent spirits from a sick person or to keep them out of a house. Most Lao Theung and Lao Sung ethnic groups are animists, for whom a cult of the ancestors is also important, although each group has different practices and beliefs. Hmong also believe in a variety of spirits (neeb), some associated with the house, some with nature, and some with ancestors. Every house has at least a small altar on one wall, which is the center of any ritual related to the household or its members.
Buddhism was introduced to Laos beginning in the eighth century by Mon Buddhist monks and was widespread by the fourteenth century. A number of Laotian kings were important patrons of Buddhism.
