The political alliance was signed there on February 19, 1921 by Polish Minister of Foreign Affairs Count Eustachy Sapieha and his French Minister of Foreign Affairs Aristide Briand, in the background of the negotiations that ended the Polish-Soviet War by the Treaty of Riga. The agreement assumed a common foreign policy, the promotion of bilateral economical contacts, the consultation of new pacts concerning Central and Eastern Europe and assistance in case one of the signatories became a victim of an "unprovoked" attack. As such, it was a defensive alliance. The secret military pact was signed two days later, on February 21, 1921, and clarified that the agreement was aimed at possible threats from both Germany and the Soviet Union. An attack on Poland would make France keep lines of communication free and Germany in check but not require it to send troops or to declare war. Both political and military pacts were legally not in force until the economic pact was ratified, which occurred on August 2, 1923.
