On February 11, 1926, a revised and consolidated edition of Mein Kampf by Adolf Hitler was published in Germany. The work — composed primarily during Hitler’s imprisonment after the failed Beer Hall Putsch of 1923 and first serialized in parts — combined autobiography with an exposition of his political ideology, including extreme nationalism, racial antisemitism, and expansionist aims. Mein Kampf set out Hitler’s view of Germany’s post–World War I condition, his rejection of parliamentary democracy, and his goals for territorial revision and German racial policy. The 1926 publication did not appear in isolation. It followed earlier fragmented publications and was timed amid the reorganization and legal rehabilitation of Hitler and the National Socialist German Workers’ Party (NSDAP) during the mid-1920s. At that time the party sought to broaden its appeal after internal setbacks and the failure of the 1923 putsch; Mein Kampf provided an ideological banner for that effort. While initial sales were modest, the book’s reach expanded in the 1930s as the Nazi movement grew in influence and ultimately seized state power in 1933. Scholars have emphasized both the rhetorical and practical significance of Mein Kampf. Rhetorically, it articulated a synthesis of conspiracy-laden antisemitism, Social Darwinist ideas, and a cult of leadership centered on the Führer principle. Practically, passages outlining territorial ambitions—particularly toward Eastern Europe—foreshadowed policies pursued after 1933, including rearmament and aggressive expansion. The book also functioned as a tool of indoctrination: after the Nazis took power, state mechanisms promoted its distribution, and editions were often given as gifts to newlyweds, civil servants, and party members. Assessments of Mein Kampf note uneven quality: its arguments are repetitive, internally inconsistent in places, and interspersed with autobiographical narrative. Yet its significance derives not from literary merit but from its role in legitimizing and publicizing an agenda that resulted in catastrophic policies once implemented. Historians caution against treating Mein Kampf as a straightforward policy manual; its value to historians lies in revealing central themes and dispositions that shaped Nazi leadership and decision-making. The book’s publication and subsequent prominence have produced enduring controversies about censorship, memory, and the ethics of making extremist texts available. Different countries and publishers have taken varied approaches over time, balancing scholarly study and disclosure against concerns about propaganda and hate speech. Contemporary editions for academic purposes typically include critical annotations, contextual essays, and warnings to help readers understand the historical context and to prevent uncritical appropriation. In short, the February 11, 1926 publication of Mein Kampf marked the consolidation of Hitler’s written program and became an influential text for the Nazi movement. Its content and subsequent use by the Nazi state contributed directly and indirectly to the ideology and policies that produced widespread repression, war, and genocide in the following decades.
