Nagmati was, according to legend, the first wife and chief queen[1] of King Ratan Sen (identified with Ratnasimha), the Rajput ruler of Medapata (present-day Mewar).

[2] Nagmati plays an important role in Malik Muhammad Jayasi's epic poem Padmavat.

In Padmavat, an epic poem written by Malik Muhammad Jayasi in 1540,[3] Nagmati is said to have been King Ratan Sen's first wife and chief queen, the head of his harem.

[4] She awaits happily as her husband returns home to Chittor, but the happiness turns to jealousy and contempt when she hears that he has taken a second wife, Padmavati, the beautiful princess of the Sinhala Kingdom.

Initially, Ratan Sen placates them by spending nights with them alternately, but then establishes peace by reprimanding them.
