World War II started in 1939 when many countries, including New Zealand, declared war on Germany when it attacked Poland.
The rise of Fascism and Hitler's need for expansion were two of the many factors that led to the Second World War. By the time it ended in 1945, almost every country in the world had been affected.
These websites will explain more about the causes of WW2 and the impacts it had worldwide.
