Why did German troops swear an oath of unconditional obedience to Adolf Hitler?

The assertion that German troops swore an oath of unconditional obedience to Adolf Hitler was not a spontaneous development, but a deliberate political maneuver orchestrated by the Nazi leadership to consolidate absolute power.

Following the death of President Paul von Hindenburg on August 2, 1934, Hitler merged the offices of president and chancellor, effectively becoming the supreme commander of the German armed forces. To cement this authority, Minister of War Werner von Blomberg—a staunch supporter of the regime—replaced the traditional military oath. Previously, troops had pledged to defend the German constitution or the fatherland; under the new mandate, they were required to swear unconditional obedience directly to Hitler.1

This change was part of a broader effort to dismantle institutional independence within the military, a process known as Gleichschaltung. By 1938, Hitler further solidified his control by forcing the resignation of senior military leaders, abolishing the Ministry of Defense, and establishing the Oberkommando der Wehrmacht (OKW) to serve as his personal staff. These actions ensured that the Wehrmacht functioned as an instrument of his dictatorship rather than a neutral state institution.23
