Norrköping 1880: Shadows of the Industrial Revolution
« Childhood is not meant for the labor of machines, but for play and instruction. »— Fredrika Bremer, Swedish writer and social reformer, 1840
Norrköping, situated on the banks of the Motala ström, established itself as a major industrial center in Sweden as early as the 17th century, but reached its peak during the Industrial Revolution in the 18th and 19th centuries. Powered by the river's hydraulic force, the city saw mills, paper factories, and especially, a flourishing textile industry prosper. It became the country's leading textile producer, employing thousands of people, making it a crucial economic engine for Sweden and earning it its evocative nickname.
However, this rapid growth was accompanied by significant social challenges. Working conditions were often difficult, days were long, and cheap labor, including that of children, was widely exploited. Young people, sometimes as young as seven, worked in factories, exposed to physical dangers and diseases, deprived of education and the carefree nature of childhood. It was in this context that voices rose for reform, gradually leading to legislation to protect workers and, ultimately, to the emergence of a strong trade union movement in Sweden.
