Explanation:

HE WROTE THE BOOK 'MEIN KAMPF' ALSO KNOWN AS MY STRUGGLES.

WHAT DID IT CONTAIN?

It was a blueprint for his future plans. Examples of what were in the books were that he wanted to get revenge from the Entente for the Treaty of Versailles. He also talks about his plans of taking over a large chunk of Europe for his 'Pure Arayan Race' to survive (Lebensraum). He did not try to hide his hatred for Jews and Communists and did not hide the fact that he thought of the Arayans as superior to others.
