What caused great britain and france to declare war on germany in 1939?
a-the appeasement policy
b-the invasion of poland
c-the nonaggression pact
d-the surrender of poland

The correct answer is B. the invasion of Poland. On 1 September 1939, Germany invaded Poland as part of the plan to retake land lost with the signing of the Treaty of Versailles in 1919. When Hitler invaded Poland, he was confident that Britain and France would continue their policy of appeasement, as they had done during his occupation of the Rhineland demilitarized zone, the Sudetenland and Czechoslovakia, and negotiate a peace settlement. However, Britain and France had signed a series of military agreements with Poland promising mutual assistance in case of military invasion from Germany; consequently, when Hitler invaded Poland on 1 September 1939, they demanded Germany withdraw from Poland or they would declare war. On 2 September 1939, as Hitler had not withdrawn his troops, Britain and France declared war on Germany.
