Why did President Paul von Hindenburg appoint Adolf Hitler as chancellor in 1933?

President Paul von Hindenburg appointed Adolf Hitler as chancellor on January 30, 1933, primarily due to political deadlock and the influence of conservative advisers who believed they could manipulate the Nazi leader.12

Following the failure of Kurt von Schleicher’s government to secure parliamentary support, Franz von Papen—seeking revenge against Schleicher—convinced Hindenburg to form a coalition government with Hitler. Papen assured the aging president that Hitler could be easily controlled, as non-Nazis would hold the majority of ministerial posts.31

Although Hindenburg had long distrusted Hitler’s "noisy aggressiveness" and had previously refused to appoint him, he was frustrated by the ongoing cabinet crises and the failure of previous governments to stabilize the Weimar Republic. Ultimately, Hindenburg succumbed to the pressure from his inner circle of military and landowning friends, who viewed the Nazis as a useful movement they could manage. This decision proved to be a catastrophic miscalculation, as Hitler quickly dismantled democratic institutions to establish a dictatorship.124
