Why did hitler keep pointing out to the getman people after world war 1

Hitler promised if he was elected chancellor he would bring Germany back to its prime. Which he basically did. After the lose of WW1 hitler was furious that Germany lost. Along with all that Germany had to repay to the allies hitler sought that it was time for Germany to become great again so he wrote Mien Kampf in prison about his struggles to bring Germany back to its glory days all he needed was the support of Germany.
