Franco-Polish alliance
In the 16th century, France and Austria fought a long rivalry that pushed French diplomats to seek allies east of Vienna. Polish King Jan III Sobieski considered an alliance with Paris against Austrian pressure during this era. The Ottoman Empire posed a greater threat than Austria at the time. This danger forced Sobieski to fight alongside Austria in the Battle of Vienna instead of joining France. By the 18th century, Russia, Prussia, and Austria had partitioned Poland out of existence. Napoleon later recreated a Polish state known as the Duchy of Warsaw. A united German Empire rose in the 19th century to become a new common enemy for both nations.
Three pacts were discussed by Polish Chief of State Józef Piłsudski and French President Alexandre Millerand in early February 1921. The political agreement was signed on the 19th of February 1921 by Count Eustachy Sapieha and Aristide Briand. A secret military pact followed two days later on the 21st of February 1921. These documents clarified that threats from Germany or the Soviet Union were the primary concern. Both agreements remained legally inactive until the economic pact was ratified on the 2nd of August 1923. Registration of the political treaty occurred on the 2nd of July 1923 under document number Dz.U. 1922 nr 63 poz. 563.
France extended the alliance through the Franco, Polish Warrant Agreement signed on the 16th of October 1925 in Locarno. This treaty subscribed all previous Polish, French agreements to the League of Nations system. Czechoslovakia had a significant economy while Poland possessed a strong army for this potential triangle. Edvard Beneš avoided signing a formal alliance with Poland to prevent taking sides in territorial disputes. Doubts about the trustworthiness of the Polish army weakened Czechoslovakian influence. France refused to invest in Polish industry or share military expertise during these years. The registration date for the Locarno treaty appeared as the 14th of September 1926 in document 1926 LNTSer 250.
The alliance remained mostly inactive throughout the 1930s despite growing German threats. Only the French Military Mission to Poland continued working with the Polish General Staff since 1919. Both countries began seeking a new pact to guarantee independence and military cooperation by the late decade. Internal political friction between supporters and opponents of Józef Piłsudski undermined Polish influence. Germany became an increasingly visible threat during the latter part of the 1930s. France showed reluctance to improve trade relations or buy agricultural products from its eastern ally.
General Tadeusz Kasprzycki and Commander Maurice Gamelin signed the convention on the 19th of May 1939 in Paris. This agreement was named after the two military leaders who negotiated the terms. The text obligated both armies to provide help if war broke out with Germany. Gamelin promised a bold relief offensive within three weeks of any German attack. The treaty required ratification of a separate political convention before it could take legal force. France ratified the treaty on the 4th of September 1939 during the fourth day of the German offensive.
France provided only token help to Poland through the Saar Offensive during September 1939. This limited response has often been considered an example of Western betrayal by historians. Foreign Minister Georges Bonnet wrote that their agreement with Poland contained gaps needed to keep France away from war. Ambassador Léon Noël stated in October 1938 that removing obligations would preserve French freedom of decision. The political convention later served as the basis for recreating the Polish Army in France. The alliance effectively ended when the Second World War began.
