Former Crown Prince Philippe was sworn in as king of Belgium on Sunday after his father abdicated the throne an hour before.

“I have noticed how my age and my health have not permitted me to exercise my duties the way I would like to,” the 79-year-old said in an address to the nation.
King Philippe, 53, was educated in public schools in Belgium’s two major languages, Flemish and French, and later attended the royal military academy, where he trained to be a fighter pilot.
Belgium, which is home to the European Union capital of Brussels, has also gained a queen in Mathilde, Philippe’s wife. She is the daughter of a count and countess and graduated with a degree in speech therapy.
Albert’s abdication follows that of the Netherlands’ Queen Beatrice earlier this year and that of Pope Benedict XVI at the Vatican.
European Commission President Jose Manuel Barroso has praised Albert for the move.
“I wish to express to him my sincere thanks for his tireless efforts in the service of Belgium and Europe,” Barroso said in a statement.
Throughout his 20-year reign, Albert “has never ceased to be a staunch defender of the values that are the basis of the European construction,” Barroso said.
The Belgian royal family has had less luck promoting cohesion within its own country, which is culturally split between ethnic Flemish Dutch people in the north, ethnic French people in the south and a small group of ethnic Germans in the east.
Separatist ideas have sprouted particularly in the Flemish region, which has a stronger economy.
