When Willem-Alexander became King: best moments

The world watched and celebrated as the Netherlands welcomed a new King and Queen, Willem-Alexander and Maxima, with open arms in what was the biggest regal gathering since the Queen's Diamond Jubilee celebrations.

Tens of thousands gathered in the festively decked-out capital of Amsterdam to welcome the country's first king in 120 years and Europe's youngest ruling royals.

Emotions ran high during the national celebrations, but no-one would have been more moved than Willem-Alexander himself and Princess Beatrix, who held hands as she signed the document of abdication in the Royal Palace, standing down from her role as queen after 33 years.

The red carpet was rolled out for the many royals who travelled from all corners of the world to celebrate the event, including British representatives Prince Charles and the Duchess of Cornwall, and their counterparts from Denmark, neighbouring Norway, Belgium, Spain, Morocco and Thailand. Even Japan's Prince Naruhito and his wife Princess Masako turned out, making her first official overseas appearance in 11 years.
