On 30 April 2013, Queen's Day, Willem-Alexander succeeded his mother Beatrix and became the first King of the Netherlands in 123 years.
Anti-German riots in Amsterdam marred the wedding day and the following observances of Koninginnedag.
Fearing further demonstrations on the holiday, government officials decided to open Amsterdam city centre to the vrijmarkt ("free market") that had long been held on Koninginnedag in the outskirts of town, principally for children.
ING Bank found in 2011 that one in five Dutch residents planned to sell at the vrijmarkt and estimated they would earn €100 per person for a total turnover of €290 million.
Over half of the Dutch people buy at the vrijmarkt; ING Bank predicted they would spend €28 each at the 2011 vrijmarkt.
The vrijmarkt occupied the space where demonstrations might have been held, and began a new custom.
