The Moriyas' western neighbours were the Koliyas, while the Mallakas lived to their east,[2] and the Sarayū river was their southern border.

[1] The capital of the Moriyas was Pipphalivana, which the 7th century CE Chinese pilgrim Xuanzang later referred to by the name of Nyagrodhavana.

[5][6] After the death of the Buddha, the Moriyas claimed a share of his relics from the Mallakas of Kusinārā, in whose territory he had passed away and had been cremated.

[1] Under the reign of Chandragupta's grandson Asoka, who was a patron of Buddhism, Buddhist writers attempted to connect Asoka to the Buddha by claiming that his ancestral tribe, the Moriyas, were descended from Sakyas who had fled from the Kauśalya king Viḍūḍabha's annexation of their state by fleeing into the mountains.

[1] Like the other gaṇasaṅghas, the ruling body of the Moriya republic was an Assembly of the kṣatriya elders who held the title of rājās (meaning "rulers"), whose sons were the rājakumāras ("princes").
