The manuscript deals with French subsidies to Sweden in the 17th and 18th centuries. It is known that Sweden received subsidies from France during parts of the 17th and 18th centuries, but most people do not know that it was 89 out of a total of 166 years from 1631 to 1796. The present study deals with the reasons why France during the period 1631-1796 repeatedly and for long periods gave Sweden subsidies, and the reasons why Sweden received them. Furthermore, the manuscript deals in detail with the effects of the French-Swedish subsidy relationship in Sweden in particular. Subsidies were part of the early modern period's way of creating alliances and therefore the French-Swedish relationship is placed in a larger international perspective where alliances with Sweden became part of a French great power strategy.
