What was the primary concern that led to Germany's entry into the Sudetenland in September 1938?

Germany's entry into the Sudetenland in September 1938 was primarily motivated by concerns about the treatment of ethnic Germans living in the region. The Sudetenland was home to a significant population of ethnic Germans who were facing increasing discrimination and political oppression from the Czechoslovak government. Adolf Hitler used this situation to justify his claim that Germany needed to protect its citizens, portraying the German-speaking population as victims of injustice.

By framing the annexation as a means of safeguarding national interests and the rights of ethnic Germans, Hitler was able to rally domestic support and present his aggressive expansionist policies as legitimate actions aimed at protecting German nationals. This narrative created a sense of urgency and moral justification for what was effectively a territorial expansion, which ultimately aligned with the broader Nazi agenda of uniting all ethnic Germans under Greater Germany.

Other options do not reflect the primary reasons for the annexation. While political pressure from the League of Nations existed, it was not a driving factor in the decision. The establishment of democratic governance was not a concern for Nazi leaders, who opposed democracy. Lastly, while there may have been some economic motivations involved in controlling the industrial resources of the Sudetenland, this aspect was secondary to the focus on ethnic identity and perceived victimhood
