World War II was a global conflict that lasted from 1939 to 1945. It involved many of the world’s major powers, divided into two opposing military alliances: the Allies (led by the United States, the United Kingdom, and the Soviet Union) and the Axis (led by Germany, Japan, and Italy). In this lesson, we will explore the basic concepts of World War II, its history, and its impact on the world.
Causes of World War II
There were many complex factors that led to the outbreak of World War II, including:
Treaty of Versailles – the harsh treatment of Germany in the Treaty of Versailles, which ended World War I, led to resentment and a desire for revenge.
Appeasement – the policy of appeasement, pursued by Britain and France, allowed Germany to rearm and expand its territories without opposition.
Expansionist policies – the aggressive expansionist policies of Japan, Italy, and Germany, which led to the invasion of China, Ethiopia, and other countries.
Key Events of World War II
World War II was marked by many significant events, including:
Invasion of Poland – on September 1, 1939, Germany invaded Poland, marking the official start of the war.

D-Day – on June 6, 1944, the Allies launched a massive invasion of Normandy, France, which became a turning point in the war.
Atomic bombings of Hiroshima and Nagasaki – on August 6 and 9, 1945, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki, leading to Japan’s surrender and the end of the war.
