'Woke' family man to become King

A rebellious teen turned "woke" family man, Denmark's future king Crown Prince Frederik is the embodiment of the country's relaxed, liberal monarchy.

A lonely and tormented teenager, Frederik resented his parents for neglecting him as they fulfilled their royal obligations. He sought solace in fast cars and fast living, and was considered a spoiled party prince in the early 1990s.

But that began to change after he graduated from Aarhus University in 1995 - the first Danish royal to complete a university education - and during his time in the military.

He has four kids with his wife Mary Donaldson - an Australian lawyer.

The couple are "modern, woke, lovers of pop music, modern art and sports," said a historian.
