I do plan to streamline to story, or even add new things.

Here's a "short" wiki about the world.

The Kingdom of Equestria faced stagnation under the Rule of the Two Alicorns; there was no incentive for progress as the nation had been under a millennium of Peace, but the world outside of the borders of the Kingdom was changing and changing fast. Many saw it, but they did not try to change it. Well, that was until Celestia's own Star Student, Twilight Sparkle, started to have enough of this Stagnation.

She fought against evils that would have destroyed the nation if it weren't for her direct involvement on it, she did so much for the Kingdom, and for that she was just given a fancy crown and a tittle of Princess of Magic, but she had no real power because the Royal sister still where the ones who controlled the nation, she felt insulted and disrespected, she had almost died many times in the name of Equestria and they basically gave her nothing.

So, she took it into her own hands to bring change, not token changes, but a real regime change. She played her cards with disinterested generals, business leaders, and other ponies of the High Echelon of Equestrian society, all of the parties having a common issue, the Stagnation of their homeland, so with that, she made a secret army of supporters, and just waited for the right time to strike.

And that time came, the military stormed the capital of the nation, Canterlot and put the sisters under arrest, twilight just walked in not wearing armor or having any weapons, she just sat on Celestia's throne and softly smiled, and with that The Kingdom of Equestria was no longer, and the Equestrian Empire Started.

Her changes where quick and brutal, the Flags where changed, New laws where created, Slavery was Allowed and institutionalized, and degenerate laws became the norm, Moderation was asked by the population, And Twilight responded with putting an iron heel on Equestrian society, becoming the head of the Empire and with that Crowned herself Empress of Equestria and all her lands.

This new Equestria was stronger that many experts expected, this ruthless and efficiency over everything kind of government brought the nation out of its age of Stagnation and into a veritable economic boom, quality of life went up, the highest in Equestrian history, but all in the price of Chains and a collar, but it was a price many creatures decided to accept and pay for it, but some, specially from the Old Equestrian Democratic movement, also known as the Equestrian Republic party did not accept this change, and shortly went underground after their political party was made illegal by Imperial decree.
