I know you can get married at 16 I believe.
Or was it 15?
Im pretty sure it would have something to do with parental consent, since they would be giving up their child. When that a region determines you to be an 'adult', your free to marry whoever you want, but until then you need your parents to sign off on it.
Not so sure on the age though, here is a list for the US:

According to this there is no minimum age for marriage, just need consent.
Generally though, varying between 16 and 18 is when you can just go for it :D
