The Sixteen Great States

In two places in the Aïguttaranikàya (Uposathasuttaü, Bk. 3.71; Vitthatåposathasuttaü, Bk. 8.42) we find the following list of great states (Mahàjanapadà): Aïgà, Magadhà, Kàsã, Kosalà, Vajjã, Mallà, Cetã, Vaüsà,01 Kurå, Paÿcàlà, Macchà, Sårasenà, Assakà, Avantã, Gandhàrà, Kambojà.
We sometimes come across other forms of this list, so that at Janavasabhasuttaü (DN 18) only the following ten are mentioned: Kàsã, Kosalà, Vajjã, Mallà, Cetã, Vaüsà, Kurå, Paÿcàlà, Macchà,02 Sårasenà. Interestingly, the Sàkiyas and the Koëiyans are omitted from these lists, perhaps they were not considered as great states, being too small in size.
