German–Polish declaration of non-aggression

The German–Polish declaration of non-aggression (German: Erklärung zwischen Deutschland und Polen über den Verzicht auf Gewaltanwendung, Polish: Deklaracja między Polską a Niemcami o niestosowaniu przemocy), also known as the German–Polish non-aggression pact, was an agreement between Nazi Germany and the Second Polish Republic that was signed on 26 January 1934 in Berlin. Both countries pledged to resolve their problems by bilateral negotiations and to forgo armed conflict for a period of 10 years. The agreement effectively normalised relations between Poland and Germany, which had been strained by border disputes arising from the territorial settlement in the Treaty of Versailles. The declaration marked an end to an economically damaging customs war between the two countries that had taken place over the previous decade.
