As a result of the Swedish Reformation, which was concluded at the parliament in Västerås 1527, the monks were expelled and the area became property of the crown.
At the end of the 16th century, Johan III (son of Gustav Vasa) established an additional brickyard on the northern bank of the island.
For example, they were allowed to set up operations there without having to belong to the guilds and they were exempted from tax for ten years.
When the Swedish Empire collapsed in the beginning of the 18th century the crown embarked on a generous economic policy to develop Kungsholmen, which was then largely empty of buildings.
In the early 19th century the military began to settle in Kungsholmen, which at the time was still a sparsely populated idyll.
When Samuel Owen settled in Kungsholmen, it had begun developing into a marked district factories and workers.
This development was accentuated when the Bolinder brothers start building up their business at Klara Sjö, west of the Kungsbron, (King's Bridge) in the mid-19th century.
The bridges Västerbron and Tranebergsbron were also built the same decade, and Sankt Eriksbron received its current dimensions.
