Treaty of Bärwalde
The Treaty of Bärwalde (French: Traité de Barwalde; Swedish: Fördraget i Bärwalde; German: Vertrag von Bärwalde) of 23 January 1631 was a treaty concluding an alliance between Sweden and France during the Thirty Years' War, shortly after Sweden had invaded Northern Germany then occupied by Ferdinand II, Holy Roman Emperor's forces. The treaty obliged Sweden to maintain an army of 36,000 troops, and France to fund the Swedish army with an annually 400,000 Reichstalers.
Sweden, who had already intervened in the Battle of Stralsund (1628), started her campaign in the Holy Roman Empire in 1630. The invasion began when Gustavus Adolphus of Sweden had landed in the Duchy of Pomerania and concluded an alliance with Bogislaw XIV, Duke of Pomerania, the Treaty of Stettin (1630). Yet, Sweden found no other ally except for the Free imperial city of Magdeburg. From the Pomeranian bridgehead, Gustavus Adolphus advanced further south into Brandenburg in early January 1631.
A Franco-Swedish alliance had been prepared since the Truce of Altmark in 1629 and agreed on in the Treaty of Västerås on 5 March 1630. On 23 January 1631, French and Swedish negotiators reached an agreement in Brandenburgian Bärwalde (now Mieszkowice) near Pomeranian Greiffenhagen (now Gryfino).
The treaty 
The treaty's stated purpose was to protect "common allies, the safety of the North and Baltic Seas, and freedom of trade" as well as the liberation of the "oppressed nobles of the empire". The treaty was scheduled to apply for five years. Its core provisions were
- Sweden was to maintain an army of 36,000 troops in Germany: 30,000 infantry, 6,000 cavalry.
- France was to pay an annual 400,000 Reichstalers (1,000,000 livres) and an additional 120,000 Reichstalers for 1630.
- France and Sweden were not to conclude peace treaties with third parties without mutual approval.
In addition, the treaty provided religious guarantees, including a guarantee for religious freedom of subdued Catholics. Another provision was that France and Sweden respect the neutrality of Bavaria and the Catholic League under certain premises, yet these premises were not fulfilled by the time the treaty was concluded.
