Introduction:
Nazism, or National Socialism, became popular in Germany by 1930 due to a combination of political, economic, and social factors. The rise of Adolf Hitler and the Nazi Party was fueled by the discontent and frustration of the German people in the aftermath of World War I and the Great Depression. This essay will explore the key reasons behind the popularity of Nazism in Germany during this period.

1. Economic Factors:
- The German economy was severely impacted by the Treaty of Versailles, which imposed heavy reparations and territorial losses on Germany after World War I.
- The Great Depression of the 1930s further worsened the economic conditions, leading to widespread unemployment, poverty, and inflation.
- The Nazi Party promised economic stability and prosperity through their nationalist and protectionist policies, appealing to those who were struggling financially.

2. Political Factors:
- The Weimar Republic, established after the abdication of the German Emperor, faced numerous challenges and lacked public support.
- The government was perceived as weak and ineffective in addressing the economic crisis and restoring national pride.
- The Nazi Party, under Hitler's leadership, provided a strong and charismatic alternative, offering a vision of a powerful and united Germany.

3. Propaganda and Manipulation:
- Hitler and the Nazi Party effectively utilized propaganda to spread their ideology and gain support.
- Joseph Goebbels, the Minister of Propaganda, employed various techniques such as mass rallies, speeches, and the use of media to create a cult of personality around Hitler.
- Propaganda campaigns targeted specific groups, such as the unemployed, farmers, and youth, tailoring messages to their specific grievances and aspirations.

4. Anti-Semitism and Scapegoating:
- The Nazi Party capitalized on existing anti-Semitic sentiments in Germany, blaming Jews for the country's problems.
- By scapegoating Jews and other minority groups, the Nazis were able to channel public anger and divert attention from the government's failures.
- Anti-Semitic propaganda and policies appealed to those who sought a sense of unity, identity, and a common enemy.

5. Weaknesses of Political Opposition:
- The Weimar Republic faced internal divisions and lacked a united and strong opposition.
- The Communist Party and Social Democratic Party, which could have been potential rivals to the Nazis, were divided and focused on their own agendas.
- This lack of effective opposition allowed the Nazi Party to gain power and popularity.

Conclusion:
In conclusion, the popularity of Nazism in Germany by 1930 can be attributed to a combination of economic hardships, political instability, effective propaganda, anti-Semitism, and the weaknesses of political opposition. The Nazi Party's promises of economic stability, national pride, and strong leadership resonated with a disillusioned and frustrated German population, ultimately leading to their rise to power.
