Like other industrialist and capitalist leaders, Alfred Hugenberg expected that it would be possible to control Hitler and use him for their own ends, but even though he served in Hitler's first cabinet he ultimately had little influence on the direction of Nazi policy.
Alfred Hugenberg's politics revolved primarily around pan-Germanism, German nationalism, and antisemitism. His political goal was the overthrow of the Weimar government, the elimination of the Weimar constitution, and the establishment of a conservative, authoritarian government which enforced traditional, Christian, German values.
Alfred Hugenberg was an elitist and capitalist at heart, but he recognized that he needed populist support for his political agenda to have a chance.
Since Adolf Hitler was the only viable populist candidate who also shared at least some of Hugenberg's views, he chose Hitler for both heavy financial support as well as extensive coverage in his various media outlets.
After the war he was declared as merely being a "fellow traveler" rather than a Nazi, so he was allowed to keep all of his property and businesses. Nevertheless, he was one of the few people without whom Adolf Hitler's rise to power would not have been possible.
