The Buddha established an order of nuns at the request of his own foster mother, Mahapajapati Gotami, after initial hesitation
The Buddha's initial refusal to ordain women, followed by his eventual agreement after his foster mother's persistence, is preserved candidly in Buddhist scripture rather than smoothed over, making the founding of the nuns' order a recorded negotiation rather than a simple decree.
Mahapajapati Gotami was the Buddha's maternal aunt and, after his mother Maya died shortly after his birth, his foster mother and primary caregiver. Traditional accounts preserved across the Vinaya Pitaka and reflected in the Therigatha describe her approaching the Buddha after her husband King Suddhodana's death, requesting ordination for herself and a group of Sakyan women, and being refused, reportedly three times, before the Buddha's attendant Ananda intervened on the women's behalf and the Buddha relented, establishing the bhikkhuni sangha with additional rules placed on nuns relative to monks. Scholars have long debated how to read the Buddha's hesitation and the extra rules that followed, whether as later textual accretion or genuine historical memory of institutional caution. What the account does establish clearly is that women's full renunciation and celibate ordination in Buddhism has a specific founding moment and a specific founding figure, not an assumed or automatic inclusion alongside the monks' order.
Historians continue to debate whether the extra rules placed on nuns, the garudhammas, reflect the Buddha's own institutional caution or later editorial additions to the Vinaya.
