Almost 40 years after he was crowned, King Juan Carlos I of Spain says it's time to abdicate, to hand over the throne to a new generation that can take on the challenges of tomorrow.
Spain is a parliamentary monarchy.
The king's role in government is mostly ceremonial, he doesn't set policy for Spain.
King Juan Carlos himself is part of the reason for that.
He helped transition Spain back to democracy in the late 1970s.
In general, he's been a popular king, but his reputation took a hit in 2012 when he went on a luxurious hunting trip as the Spanish economy was in a deep recession.
So, who will be Spain's new king? That honor will go to Crown Prince Philippe.
Juan Carlos says his 46-year old son has the maturity, the preparation and the sense of responsibility needed to serve as king.

Some $3 billion journeys we are taking last year.
With those trips went the hopes and dreams of deals to be done, families to be reunited, ambitions to be realized.
The entrepreneurial spirit of risk taking spawn by the earlier pioneers continued as more and more airlines took to the skies.
Pan American world airways blaze the trail across the Atlantic with jet aircraft and trumpeting service.
A new concept in air transportation, the travail has been taken out of travel.
A smooth ride for passengers it might have been, but for the airline the concept of risk and reward eventually went into reverse.
Pan Am couldn't survive.
