Talk:Twilight's Kingdom - Part 1/@comment-24466982-20140629135039/@comment-10390252-20140701155526

I've always liked Reality Check's explanation for this in his fan-fiction 'The Great Alicorn Hunt' on FIMFiction.net. Basically, the Alicorns are seen as 'the divine race' and automatically worthy of ruling over the rest of ponykind.

In that story, Celestia tells an amusing story of how, after defeating Discord, they fled the attention of all their pony 'worshippers' into the Everfree Forest and hid in a cave. They went to sleep for a century, hoping all the fuss would have died down in that time. When they woke up, they found that the ponies had found them and built the Castle of the Royal Pony Sisters around them whilst they slept!

Although this is only a fan-fiction, I wouldn't be surprised if there is something like this going on in the show too. Basically, even if Celestia hadn't made Twilight a princess, the fact that she was an alicorn would mean that most ponies would treat her like a princess. Celestia just decided to short-circult the whole stupid 'Cult of Twilight' thing by making it official as quickly as possible to prevent uncontrolled outbursts by stupid ponies who think that making Twilight their God-Queen would somehow 'please' her.
