A thousand years ago, it was foretold that Nightmare Moon would return in a thousand years. Two years after those events, Twilight Sparkle was informed that one thousand years ago, Luna and Celestia defeated King Sombra. But other, less known events happened one thousand years ago as well. This is one of them. One thousand years ago, Celestia held a council meeting in preparation for the one thousand year celebration of the Royal Sisters' reign.
