Propaganda played a pivotal role in securing public acceptance of Hitler's new title as Führer following President Hindenburg's death. The Nazi propaganda machine, led by Joseph Goebbels, launched a widespread campaign to glorify Hitler and present the merger of the Chancellor and President's roles as a natural and positive development for Germany. This propaganda emphasised the unity and strength that Hitler's leadership brought to the nation, portraying him as the embodiment of German aspirations. The regime's control over media and information also meant that dissenting voices were silenced, ensuring that the public narrative was overwhelmingly in favour of Hitler's new title. This manipulation of public opinion was crucial in legitimizing Hitler's absolute power in the eyes of many Germans.

The Night of the Long Knives significantly strengthened Hitler's position with the German Army. By eliminating the SA's leadership and reducing its power, Hitler appeased the Army, which had viewed the SA as a rival and a threat to its traditional role in German society. The Army was concerned about the SA's growing influence and its potential to supplant the military's position. After the purge, the Army’s allegiance to Hitler solidified, as they saw him as a stabilizer and protector of traditional military values. This realignment of the Army's loyalty was critical for Hitler, ensuring military support for his regime and further consolidating his power.

The Night of the Long Knives represented a significant turning point in the internal dynamics of the Nazi Party by shifting the balance of power firmly to Hitler and his loyalists. Prior to the purge, the SA, under Ernst Röhm, had posed a significant challenge to Hitler's authority due to its size and independent streak. The purge not only eliminated this challenge but also served as a warning to others within the party about the consequences of dissent. It established a precedent for absolute loyalty to Hitler and signalled the end of any semblance of internal democracy or debate within the party. Post-purge, the party's structure became more centralized and hierarchical, with Hitler at the apex, commanding unquestioned authority.

The immediate political consequences of the Enabling Act for the Weimar Republic were catastrophic, leading to its effective dissolution. The act allowed Hitler's government to pass laws without the Reichstag's consent or the president's signature, bypassing the constitutional framework of the Republic. This usurpation of legislative power by the executive marked the end of democratic governance in Germany. It led to the centralization of power in Hitler's hands, as the Nazis could legislate without checks and balances. Political parties were subsequently banned, and all opposition was suppressed, transforming the Weimar Republic from a democracy into a totalitarian state under Nazi rule.

The Reichstag Fire Decree, issued in response to the Reichstag Fire in 1933, was a crucial tool for the Nazi regime to suppress political opposition. This decree suspended several key civil liberties, such as freedom of speech, press, and assembly, which were essential components of democratic functioning. By curtailing these freedoms, the Nazis effectively muzzled the opposition, particularly communists and social democrats, who were their main rivals. The decree also allowed for the arrest of political adversaries and the banning of their publications, severely limiting their ability to organize and resist. This created an environment where the Nazis could operate with little to no opposition, consolidating their power significantly.
