In the 1920s, many in the leadership of Weimar Germany, who felt humiliated by the conditions that the Treaty of Versailles had imposed after their defeat in the First World War (especially General Hans von Seeckt, chief of the Reichswehr), were interested in cooperation with the Soviet Union, both in order to avert any threat from the Second Polish Republic, backed by the French Third Republic, and to prevent any possible Soviet-British alliance. The specific German aims were the full rearmament of the Reichswehr, which was explicitly prohibited by the Treaty of Versailles, and an alliance against Poland. It is unknown exactly when the first contacts between von Seeckt and the Soviets took place, but it could have been as early as 1919–1921, or possibly even before the signing of the Treaty of Versailles.[12][13]
