Saṅghamittā was an Indian Buddhist nun and believed to be the eldest daughter of Emperor Ashoka and his first wife and Empress, Devi. Together with her brother Mahinda, she entered an order of Buddhist monks. The two siblings later went to Sri Lanka to spread the teachings of Buddha at the request of King Devanampiya Tissa who was a contemporary of Ashoka. Ashoka was initially reluctant to send his daughter on an overseas mission. However, because of the insistence of Sangamitra herself, he finally agreed. She was sent to Sri Lanka together with several other nuns to start the nun-lineage of Bhikkhunis at the request of King Tissa to ordain queen Anulā and other women of Tissa's court at Anuradhapura who desired to be ordained as nuns after Mahindra converted them to Buddhism.
