Why was "All Quiet on the Western Front" banned in Germany during the 1930s?

The decision to ban "All Quiet on the Western Front" in Germany during the 1930s stemmed from its portrayal of the harsh realities and disillusionment of war, which directly contradicted the nationalist and militaristic ideals promoted by the Nazi regime. The novel presents a graphic depiction of the experiences of soldiers during World War I, highlighting themes of suffering, trauma, and the futility of war. These themes were at odds with the glorification of militarism that the Nazis sought to foster, leading them to label the book as politically controversial. The regime aimed to suppress voices and literature that criticized warfare and the romanticized notions of heroism associated with it, especially amidst their efforts to reshape German society and ideals following the turmoil of the war. As a result, the book was seen as a threat to the regime's narrative and subsequently banned. This significant political controversy surrounding the book's subject matter and its implications for German identity during that era is why it stood out as a target for censorship.
