Only Queens have sat on the throne of the Netherlands since the 1800s.
The last two Queens of the Netherlands have both abdicated in favour of their daughters:
- In 1948 Queen Wilhelmina abdicated after 50 years on the throne which spanned two World Wars.
- Her daughter Queen Juliana abdicated in 1980.
Prince Willem-Alexander would become the first king since King Willem III died in 1890, if his mother Queen Beatrix does abdicate tonight.
