Around what time did World War 2 take plac?
WWII broke out officially on September 1, 1939, and ended on
September 2, 1945, with Japan's surrender. Germany had already
surrendered in May 1945.
However, the years 1933-1939 were clearly leading to the war,
with Hitler preparing his country for a war. For example, Germany
"invaded" Austria already in 1938 (its troops were welcomed by the
Austrian people, with no fighting taking place).
