Hitler's aim to unify Austria and Germany is known as Anschluss, meaning union
In 1934, Hitler's first attempt at Anschluss was thwarted by Italian objections, fearing an enlarged Germany on their border
By 1938, Hitler launched his second attempt at Anschluss, leading to the Anschluss with Austria on March 12, 1938
The Austrian Chancellor tried to preserve the country from German invasion by cooperating with Hitler, leading to the German-Austrian Agreement of 1936
Hitler ordered Austrian Nazis to create trouble to pressure Schuschnigg, allowing him to justify marching German troops into Vienna to restore peace
The Anschluss with Austria strengthened Hitler by:
Making Germany stronger by adding sevenmillion people and an army of 100,000 to the German Reich
Overturning a section of the Treaty of Versailles that had forbidden union between Austria and Germany
Convincing Hitler that France and Britain were weak and would not interfere with his plans
Boosting Hitler's popularity and prestige within Germany
Demonstrating the effectiveness of the alliance between Germany and Italy
The Anschluss with Austria demonstrated that the new alliance between Germany and Italy was working, as Mussolini had allowed Hitler a free hand in Austria in 1938
