The development of the Mahavidyas represent an important turning point in the history of Shaktism as it marks the rise of the Bhakti aspect in Shaktism, which reached its zenith in 1700 CE. First sprung forth in the post-Puranic age, around 6th century C.E., it was a new theistic movement in which the supreme being was envisioned as female. A fact epitomized by texts like Devi-Bhagavata Purana, especially its last nine chapters (31-40) of the seventh skandha, which are known as the Devi Gita, and soon became central texts of Shaktism.
Shaktas believe, "the one Truth is sensed in ten different facets; the Divine Mother is adored and approached as ten cosmic personalities," the Dasa-Mahavidya ("ten-Mahavidyas"). As per another school of thought in Shaktism Mahavidyas are considered to be form of Mahakali. The Mahavidyas are considered Tantric in nature, and are usually identified as:
