Sweden once operated a global network of colonies, forts, and even pirate-led ventures.
In short: While rarely remembered as a colonial power, Sweden maintained overseas territories from the 17th to the 19th centuries. From the Delaware River to the Gold Coast of Africa and the Caribbean, the Swedish empire experimented with fur trading, slave commerce, and even a failed partnership with Madagascar-based pirates.
Sweden’s colonial ambitions began in 1638 with the founding of New Sweden along the Delaware River. Established by the Swedish South Company, this venture sought to replicate the success of other European trading empires through tobacco and fur. The colony, which spanned parts of modern-day Delaware, New Jersey, Pennsylvania, and Maryland, became a cultural bridge; settlers introduced the log cabin design to America. Despite its early promise, the territory was conquered by the Dutch Republic in 1655, though the settlers retained significant local autonomy until the English took control in 1664.
In Africa, Sweden held a series of forts on the Gold Coast between 1650 and 1663, including Carolusborg, which served as a hub for a nascent slave trade. This trade was later rejuvenated in 1784 when King Gustav III acquired Saint Barthélemy from France. Unlike the rigid religious laws of the Swedish mainland, where Lutheranism was strictly enforced, Saint Barthélemy became a haven for religious diversity. By 1787, the island hosted hundreds of Catholics and various Protestant denominations, with the government even subsidizing a Catholic priest to serve the population.
The empire’s reach was often precarious and sometimes bizarre. In 1714, a group of 1,400 pirates operating out of Madagascar approached Sweden, offering to hand over the island as a colony in exchange for protection. Although the Swedish government engaged in serious negotiations and even appointed a pirate, William Morgan, as governor, the project collapsed in 1721 due to financial failures and the death of King Charles XII. Other ventures were equally fleeting; a trading post at Porto Novo in India was destroyed by French and British forces just one month after its 1733 construction.
The longest-held Swedish colony was Saint Barthélemy, which remained under Swedish rule for 94 years until its sale back to France in 1878. The legacy of these efforts is complex, ranging from the Guadeloupe Fund—a financial arrangement that saw Sweden receiving payments until 1983—to the enduring architectural influence of the log cabin in North American history.
