I'm thinking that the timeline is something like this:

 About 2,000 years ago 


 * Unification of the three tribes;


 * Starswirl asks Luna and Celestia to rule over Equestria;


 * War against the Sirens; Adagio, Aria and Sonata exiled to Earth;


 * Scorpan betrays Tirek, who is captured and imprisoned in Tartarus.

 About 1,500 years ago 


 * Reign of Discord;


 * Creation of Plunderseeds;


 * Celestia and Luna acquire the Elements of Harmony.

 About 1,000 years ago 


 * Rise of Sombra;


 * Disappearance of Crystal Empire;


 * Luna becomes Nightmare Moon and is exiled to the Moon for 1,000 years.
