Shakyas were a population native to the north-east Gangetic plain who were unrelated to the Iranic Sakas. Statehood By the sixth century BCE, the Shakyas, the Koliyas, Moriyas, and Mallakas lived between the territories of the Kauśalyas to the west and the Licchavikas and Vaidehas to the east, thus separating the Vajjika League from the Kosala kingdom. By that time, the Shakya republic had become a vassal state of the larger Kingdom of Kosala. During the fifth century itself, one of the members of the ruling aristocratic oligarchy of the Shakyas was Suddhodana. Suddhodana was married to the princess Māyā, who was the daughter of a Koliya noble, and the son of Suddhodana and Māyā was Siddhartha Gautama, the historical Buddha and founder of Buddhism. During the life of the Buddha, an armed feud opposed the Shakyas and the Koliyas concerning the waters of the river Rohiṇī, which formed the boundary between the two states and whose water was needed by both of them to irrigate their crops. The intervention of the Buddha finally put an end to these hostilities. After the death of the Buddha, the Shakyas claimed a share of his relics from the Mallakas of Kusinārā on the grounds that he had been a Shakya. Conquest by Kosala Shortly after the Buddha's death, the Kauśalya king Viḍūḍabha, who had overthrown his father Pasenadi, invaded the Shakya and Koliya republics, seeking to conquer their territories because they had once been part of Kosala. Viḍūḍabha finally triumphed over the Shakyas and Koliyas and annexed their state after a long war with massive loss of lives on both sides. Details of this war were exaggerated by later Buddhist accounts, which claimed that Viḍūḍabha exterminated the Shakyas in retaliation for having given in marriage to his father the slave girl who became Viḍūḍabha's mother. In actuality, Viḍūḍabha's invasion of Shakya might instead have had similar motivations to the conquest of the Vajjika League by Viḍūḍabha's relative, the Māgadhī king Ajātasattu, who, because he was the son of a Vajjika princess, was therefore interested in the territory of his mother's homeland. The result of the Kauśalya invasion was that the Shakyas and Koliyas merely lost political importance after being annexed into Viḍūḍabha's kingdom. The Shakyas nevertheless soon disappeared as an ethnic group after their annexation, having become absorbed into the population of Kosala, with only a few displaced families maintaining the Shakya
