IIRC the reason the queen is such a powerful piece is because the original piece was called something like "The Commander" or "The Champion", and the idea of that being a separate person from the King didn't make sense once the game reached Europe amid the chivalric code and specific rules about how lords and monarchs are to be handled on the battlefield.
You're probably after the vizier. Apocryphally, the queen's moves as currently seen originated when Queen Isobella I of Spain was pissed that the queen was a weak piece, it did indeed arise in Spain during her reign, whether for that reason is left to the reader's imagination.
Legal age for marriage has been 18 since 1978. Unlike many states in USA.

5 states have no official minimum age, but still require either parental consent, court approval or both: California, Mississippi, New Mexico, Oklahoma, and Washington.
2 states have a minimum age of 15: Hawaii and Kansas.
The real story is how a king as old and frail as him managed to get a queen as young, fit and loyal as her, willing to slay anything that appears within her sight...
