history: I would love to see a performance by the Royal Ballet. That's nice. Did you know that was founded back in 1931, and became the flagship ballet for Britain in 1956? Wow! I had no idea they had been around that long.  What else can you tell me about them? Even after being around for so long, they are still on the most famous ballet companies in the world. I would imagine so.  Do they perform globally?
knowledge: The Royal Ballet is an internationally renowned classical ballet company, based at the Royal Opera House in Covent Garden, London, England.
