Timeline

This is a list of historical events placed in the Selenial Calendar.

The Selenial Calendar pegs the latest Canterlot eclipse as day 1 of the year 1001. The reasoning for this is the mythological departure of Princess Luna a thousand years before, although her departure happened in the early 7th century of the common era.

## Ancient times

* Agriculture is invented, causing various sedentary ungulate cultures to start appearing throughout Equus. Grasses become domesticated and are increasingly bred for their easy to digest seeds over their more fibrous, harder to digest stems and leaves.
* Over time, the digestive systems of ungulates become more adapted to their increasingly grain-rich diet rather than their traditional diet of wild pastures. Ruminants stop needing to chew their cud as a more grain-based diet doesn't need extended fermentation to be digested. Fire and cooking made food even easier to chew and digest.
* Ponies live in the lands of northern Equestria in family clans and towns.
* Hetra is founded.
* Donkeys and Zebras live in Zebrica.

## 4th millennia before the common era

* According to Equestrian legend, a technologically advanced Pony empire exists at this point, which split between the three major Pony races, each carrying one of its major inventions: Earth Ponies got the plow and used it to grow lush crops everywhere the sun touched, Pegasi got the sailboat and used it to trade across the seas and Unicorns got writing and used it to research the phenomenon of Magic.

## 3rd millennia before the common era

* Assum is a kritarchy.
* Zebra traders build a trading factory in the plains east of Hetra and southwest of the eventual location of Ponyville.

New countries spring from the fallen empire: the Kingdom of the Unicorns, the Stratocracy of the Pegasi and the Republic of the Earth Ponies. These three countries are collectively known as the three tribes.
* After the fall of Grogar's empire, Crystal City expands its territory and starts growing its crystal mining industry.
