Siwesin

Siwesin (sɪ ˈwɛ sɪn) is the name for a group of ethnicities that centered around the western Perocadh Peninsula and developed their own unique cultures and languages prior to the larger consolidations of the Classical Era on Kakhor.

Similarities
There are three recognized ethnic groups considered to be Siwesin in origin: the Letese, Kennese, and Toronian. All three of these groups had many cultural, linguistic, and religious ideas in common.

In terms of language, all Siwesin languages share a root in Siwesiwin, a proto-language believed to be of the Perocadh Group about which is little is known, but from which each of the later Siwesin languages is primarily derived. In fact, it's possible to hear similar roots between the languages and speakers of sibling languages could often get the main ideas from a foreigner's conversation (Similar to Italian and Spanish similarities on Earth).

Religiously, Siwesin people are unified by a belief that each family has a unique god, who is a patron of the family trade. Wives ceremoniously leave their diety at marriage to come into the husband's family entirely. Families of similar trade considered themselves relatives, and so each trade had a collection of similar, yet unique "brother-gods".

The religious environment led to a rich and starly divided class system based on occupation, which influenced the rise and fall of dynasties, governmental ideas, and innovations.

Historical Perspective
In early times, the Siwesin people settled in the central Perocadh Peninsula, one of the first peoples to actively cross the Perocadh Mountains both north and south, taking advantage of the many passes in the western peninsula. The first recorded states in the area date to shortly after the rise of the Ushanghali Empire, when Siwesin people started trading with the Peroatlans in Retcalha, Peroth, and Ushanghal-alha; as well as the Fesha people. Even from the -3200s the Siwesin were devoted to trade, having a prime, central location between the eastern, western, and southern hubs of civilization at the time.

Several states rose and fell in the Perocadh mountains and the surrounding hillcountry until the -2500s, when the consolidation of Peroth in the northeast led to continued pressure on the valued trade routes. The explosion of the Fezhachez empire, too, had an impact on the Siwesins. Gradually, all of the Siwesin people were absorbed into the Perothan Empire, but continued to live culturally separate lives from their masters.

It wasn't until the -1800s and -1700s when Atlass conquered the Peninsula from Peroth that Siwesin culture gradually integrated into the Peroatlan sphere. Over a -1300 year occupation, The local languages became secondary, and Atlan gods and customs became the norm.

There was a brief cultural revival in -100 with the fall of Atlass and the cession of the Peninsula to Thekha, but this was thwarted by the turmoil and upheaval of the Cadh War a century later. After this, The Thekhan culture, a blend of Khanakh and Atlan roots, assimilated the remaining Siwesin people by around 450.
