Moggallāna I was King of Anuradhapura in the 6th century, whose reign lasted from 497 to 515.
After defeating his brother Kashyapa I in a civil war, he replaced Kashyapa as King of Anuradhapura, and was succeeded by his son Kumara Dhatusena.
The latter school had monks (bhikkhu) as well as nuns (bhikkhuni).
Moggallāna I "built a shelter for (them and) called it Rājinī" (Queens [abode]).
