'Mein Kampf' is the autobiography of:

"Mein Kampf" (German for "My Struggle") is the autobiographical book of Adolf Hitler, the leader of Nazi Germany. It was written in German and published in two volumes, in 1925 and 1926.

How the book was written:

• Hitler dictated most of the first volume while he was imprisoned in Landsberg Prison, Bavaria, after the failed "Beer Hall Putsch" in Munich in November 1923.
• His fellow prisoner Rudolf Hess helped him by typing and editing the manuscript.

About the book:

It describes Hitler's early life in Austria, his experiences in World War I, and the founding of the Nazi Party.

It sets out his political ideology, including extreme nationalism, racism, antisemitism, hatred of communism and the idea of "Lebensraum" (living space) for Germans in Eastern Europe. These ideas later led to World War II and the Holocaust.

After Hitler came to power in 1933, millions of copies were sold or distributed in Germany.

After World War II, the Bavarian state government held the copyright and did not allow it to be republished in Germany. After the copyright expired at the end of 2015, an annotated critical edition was published in 2016.
