Mangayarkkarasiyar (Tamil:மங்கையர்க்கரசியார்) was one of the 63 Nayanmars or holy Saivite saints who are revered in South India. She is one among the only three women who attained this distinction. Her devotion to Lord Shiva is recounted in the hagiographic poem Periyapuranam compiled by Sekkizhar as well as in the Tiruthhthondar Thogai written by the poet-saint Sundarar.
Mangayarkkarasiyar was born as a Chola princess in Pazhayarai. Her real name was Maani. She married the Pandyan Dynasty King Koon Pandiyan who ruled Madurai. She came to be known as "Mangayarkkarasiyar" (meaning queen of the women in Tamil) on account of being an ideal Queen who commanded great respect and admiration among her subjects.
She was an ardent devotee of Lord Shiva and remained a staunch Shaivite in her country which was becoming increasingly influenced by Jainism. Her husband, the Pandyan King had converted to Jainism and this worried her a lot. The King became a Jain fanatic and even forbade her to wear Thiruneeru on her forehead. Hindus suffered persecution and Having converted the king, the Jain monks started to wield greater power in the kingdom. She feared that if left unchecked, the spread of Jainism would wipe out Shaivism entirely from Madurai. Her only solace was the Prime Minister of the kingdom, Kulachirai Nayanar who still remained a staunch Shaivite. The Prime Minister sympathized with the Queen and they were both deeply concerned about the spread of Jainism and the atrocities committed by the Jain monks in Madurai.
