In the theology of the Latter Day Saint movement, an endowment refers to a gift of "power from on high", typically associated with the ordinances performed in Latter Day Saint temples. The purpose and meaning of the endowment varied during the life of movement founder Joseph Smith. The term has referred to many such gifts of heavenly power, including the confirmation ritual, the institution of the High Priesthood in 1831, events and rituals occurring in the Kirtland Temple in the mid-1830s, and an elaborate ritual performed in the Nauvoo Temple in the 1840s.
