Princess Twilight Sparkle ascended when she gained a complete and total understanding of all things magic. In the process she was granted wings, becoming an alicorn. Thus began the reign of the Princess of Magic.
Not long after, Princess Applejack ascended when she gained a complete and total understanding of all things apple. In the process she was granted wings, becoming a pegasus. Thus began the reign of the Princess of Apples.
The ascension of Rainbow Dash occurred many years later. She flew at such a speed that the laws of the universe were forced to rewrite themselves to better fit within the frame of her impossibility. In the process she was granted wings, becoming a double pegasus. Thus began the reign of the Princess of Going Fast.
More please, these double wings really killed it.
God save the Princess of Going Fast.
Common misconception. While twilight did in fact become the princess of friendship, and friendship is magic, magic is not friendship.
Friendship is in fact a previously undiscovered branch of relationship-related magic, similar to the much more explosive love magic. Friendship magic instead is a ray, similar to a laser blast. Both however are very good at making bubbles.
And while Twilight was and still is very skilled at magic, she was nowhere near a total understanding of it. Or friendship for that matter. She became a princess because Celestia was there when she died from being deatomized by friendship lasers (this was how she discovered them, in fact), and was brought back to life under the condition of taking care of all of Celestia's troubles from then on.

Yes, and Applejack also never became the princess of apples.

I think your comment wouldn't have gotten that downvote if you had stopped after the second paragraph.
