Star Swirl the Bearded probably invented the spell that turned Celestia and Luna into Alicorns. I speculate that Celestia and Luna's parents were ordinary unicorns. A few years after the founding of Equestria, the leaders of the pegasi, unicorns, and Earth ponies urged Star Swirl to find new leaders for Equestria, and "the Bearded" selected Celestia and Luna to be the recipients of an experimental new spell that turned them into "winged unicorns" or "horned, spell-casting pegasi." Celestia and Luna obtained the natural ability to turn other ponies into Alicorns (e.g. Cadance and Twilight). Cadance inadvertently turned her daughter Flurry Heart into an Alicorn by giving birth to her and accidentally casting the same spell on Flurry Heart.
