About Devadatta

Devadatta was by tradition a Buddhist monk, cousin and brother-in-law of Gautama Siddhārtha, the Sākyamuni Buddha, and brother of Yashodhara, wife of Prince Siddhartha. Devadatta was a koliyan and sakyan and is said to have parted from the Buddha's following with 500 other monks to form their own Sangha, most of whom are said to have been Shakya clan relatives of both Devadatta and Siddhartha.
