2200-2000

• Circa 2200: Earliest archeological evidence of the Kotosh Culture using pottery at a significant scale, though small artifacts exist from as far back as 2400. Disputed evidence of wheels.
• Circa 2150: Archeological records begin to show the steady expansion of the Kotosian irrigation system along the Fusang coast. It's likely wheels played a role in this construction.
• Circa 2100: The Kotosian population, especially in the city of Caral starts to boom in tandem with an apparent increase in the intensity of agriculture.
• Circa 2050: The first significant Kotosian settlements outside the four river valleys that constituted the cradle of their civilization start to emerge, beginning the era of Kotosh Expansion. To survive, these new settlements rely on intensive irrigation, heavy fishing, and trade with other Kotosian settlements.
• 2032: The mythical date of the founding of Kotosia, according to records recovered from the Caral Archives. This date is also used as year 1 in the Kotosh Calender
• Circa 2000: By this point, surging populations lead the Kotosh to expand further, mostly along the Fusang coast. Domesticated llamas start to appear, especially in the farmland surrounding Caral and other population centers.

1999-1500

• Circa 1950: As the Kotosians continue to expand into their homeland (called Jiayuan), settlements start to show up further and further afield, including the first evidence of what would become the Zhongkotosh and Beikotosh settlements.
• Circa 1900: the Zhongkotosh and Beikotosh settlements continue to expand in tandem with the ones in Jiayuan. Primitive aquaculture begins to emerge in the largest coastal settlements, along with larger and larger ships as the Kotosh get better at seafaring.
• Circa 1850: Settlements in Zhongkotosh and Beikotosh grow more independent from Jiayuan, and are at least partially self-sufficient and independent, with Zhongkotosh even boasting the eponymous city of Zhongkotosh.
• Circa 1850: The earliest written records begin to appear in the Caral archives. Larger public works projects and evidence of small conflicts indicate the beginning of the consolidation of the Jiayuan into Kotosia.
• 1823: The earliest dated record appears in the Caral archives, referencing the exploits of Huoluotuo, the ruler of Caral who is said to have expanded the city's influence.
• Circa 1800: Conflicts between Kotosian cities appear to start to escalate, especially in the Lanhe river valley where records indicate Caral has subjugated several other cities. Dated records continue to appear in the Caral archives, but they are incomplete and sometimes contradictory and don't include the names of any rulers.
• 1786: Under the leadership of Mianshe, the Caralians finish their conquest of the Lanhe river valley by defeating the coastal city of Cushi. Most historians agree that by this point, Kotosia could be considered a functioning nation-state, with control over several major cities.
• Circa 1750: Zhongkotosh and Beikotosh continue to grow, with several notable cities begging to emerge in both. Although Zhongkotosh the city still dominates the region, Kotosians have expanded as far inland as Lake Titicaca.
• Circa 1750: The first permanent settlers arrive at the Huale river, making it the fourth theatre of the Kotosh culture, after Jiayuan, Zhongkotosh, and Beikotosh.
• Circa 1750: Despite lack of settlement, by this point, the Kotosh had begun to trade with the people who would become the Olmecs in Zhongfusang.
