denmark has a queen, she's been queen since the early 70s when her father died. she is married to a french count named henri, since he's french, he's not the king, he's the prince regent.

the queen and prince henrik had two sons--frederik and joachim. frederik is the crown prince and will take over as king in denmark when his mother dies (seems like kind of a harsh way to get your job, but true nonetheless). frederik turned 40 last year and he's married to an australian girl named mary that he met at the olympics in sydney in 2000. she worked at microsoft when i did, so i've partied with her. they got married in 2004 and have since had two children.

their son, christian (all the danish kings are alternating frederik or christian), will be crown prince when his father takes the throne. they also have a daughter, isabella. here they all are, on the balcony at amailenborg (that's the royal residence in copenhagen) waving to the public on the queen's birthday in april last year.

here's one more official shot of mary--she makes a lovely princess for a girl from tasmania.
like most families, the royal family has a brother they don't like to mention. that's the younger prince, prince joachim. he was married to a lovely girl from hong kong, alexandra, and they had two children--princes nicolai and felix. then alexandra, who is a lovely, intelligent, accomplished woman noticed that joachim is a complete inbred dufus and actually quite creepy and he smokes like a chimney so they divorced in 2005. now she's remarried to a totally cute camera guy and is a countess instead of a princess. i'm sure she's thinks it was worth it to lose the title.

of course joachim didn't want to be alone for long and he wanted to try to duplicate his brother's success, so he imported a new princess, named marie, from switzerland. she's the spitting image of mary, but has a cute little french accent. they just had a son a week or so ago, so there's a new little prince. this is from their wedding last year.
princess marie seems like a nice girl and i guess you will put up with a lot to be a princess and get to wear a tiara for real, because joachim is no less creepy than he's always been.
the danish royal family is related to most monarchies in europe. one of the queen's sisters is the exiled queen of greece. even the last russian tsar's mother was a danish princess (dagmar, neé tsarina alexandra). there's lots more here if you want to learn more.
