Which country paid Sweden subsidies under the 1631 Treaty of Bärwalde? The answer is France. The treaty made French financial support the foundation of Sweden’s continued intervention in the Thirty Years’ War.
France, guided by Cardinal Richelieu, wanted to contain the power of the Habsburg dynasty without immediately fighting a major continental war itself. By subsidizing King Gustavus Adolphus of Sweden, France encouraged a powerful Protestant army to operate in the Holy Roman Empire and put pressure on Austria and Spain’s strategic interests.
Under the agreement, France promised Sweden 400,000 Reichsthalers each year for five years. Sweden in return undertook to maintain an army of roughly 36,000 soldiers in Germany. The Venetian Republic agreed to reimburse France for part of the expense because Venice also viewed Habsburg power as a threat, especially in northern Italy.
The treaty therefore belongs to the wider pattern of indirect or proxy involvement in the war. France was Catholic, while Sweden was Protestant, but their shared opposition to Habsburg dominance mattered more than confessional alignment. France later intervened directly and concluded a new agreement with Sweden in 1635.
