The Bepatj was a large but shortlived Riverine confederation, comprising of much of the land in the Lower section of the Great River. It was founded by the various Riverine splinter states of the 1st Dynasty, through a slow process of consolidation and unification. It was an empire that greatly prioritized learning and education, and founded numerous Great Libraries across its territory.
The states (along the Great River) that would join together to form the Bepatj. Note the Oraculate to their south-west
It would engage against the Oraculate in the First Oracular War, which it would lose handily, and with it, lose Ksy. These conquests would trigger the Second Oracular War and its follow-up, the Third Oracular War, in which the Bepatj and the Wajahe 6th Dynasty would work together to defeat the Oraculate, from which the Bepatj took significant conquests. However, the Bepatj was significantly weakened by these conflicts, and would soon be conquered by the 6th dynasty in turn - its conquests into the Ejee would not last for 2 decades. The collapse and subjugation of the Bepatj would result in the Decline of the Riverine Civilization.
The Bepatj prior to the First Oracular War
The Bepatj after the First Oracular War. Note the formation of the Wajahe 6th Dynasty to the north
The Bepatj after the Third Oracular War. The Ejee conquests would not last when the 6th Dynasty invaded the Bepatj, these territories would rise in rebellion under the Nodotto banner, before themselves being conquered by the 6th Dynasty as well.
The Bepatj was a major state but lasted, in total, less than one century - from its formation in 2541 to its collapse in 2637. It demonstrated, in clear terms, the inability of the Rivermen to field militaries that matched the rapidly modernizing states surrounding them; and additionally, was an early symptom of cultural decline.
