Historically it's not a queen but a general. Hence the term "promotion".
Is it strange that you marry your pawn when it reaches the other side?

Remember that pawns can also become knights or rooks: this used to be considered socially unacceptable, but times are changing. (Few pawns become bishops these days - being confined to half the squares is not very popular anymore).

Even funnier in Shogi (japanese chess): Most pieces can promote, with individual promotion rules for each of them.

japanese have some weird practices...
Does Chess support gay marriage? Or transgender operations? Or are all pawns female? That'd be really sexist.
