Answer:
When Hitler first came into power in 1933, he would fulfill his promises from all his campaigning to the German peoples.
-Started Civil Projects such as the creation of the Autobahn
-Established a free healthcare system
-Established Social Security
-Motivated industries such as BMW, Volkswagen, Mercedes, Coca-Cola (Germany), etc.
These projects made Hitler even more popular and also lifted Germany out of the Great Depression that struck in 1929. Later on, his actions would be to militarize Germany and start expanding.
-Militarizing the Industrial heart of Germany that had been occupied by French forces. (Rhineland) 1936
-The Anschluss of Austria in 1938
-Annexation of Memel in 1939
-Annexation of the Sudetenland in 1939 than the rest of Czechoslovakia.
These aggressive actions were justified by "bringing ethnic Germans living in those nations back to Germany." At the end of World War 2, Hitler had imposed a massive conscription. Which allowed for 12-17 year old boys to fight for Germany and the older population as well that were not fit for any combat.
