The National Socialist German Workers' Party(Nationalsozialistische Deutsche Arbeiterpartei, abbreviated NSDAP), also known as the Nazi Party, was a German political party. It was started in 1920 from the Deutsche Arbeiterpartei (German Workers' party) (DAP), which would later be renamed the NSDAP.

The party that came to be known as the Nazi Party was the National Socialist German Workers Party (NSDAP). Here is a detailed explanation:

- The Nazi Party, or the NSDAP, was a far-right political party that emerged in Germany in the early 1920s. It was founded by Anton Drexler, a locksmith, in 1919 as the German Workers Party (DAP). However, it was not until Adolf Hitler joined the party in 1920 and assumed leadership that it gained significant influence and popularity.

- Initially, the party was focused on nationalist and anti-Semitic ideologies. However, under Hitler's leadership, it gradually adopted a more radical and extremist agenda, including the goal of creating a totalitarian state and promoting Aryan supremacy.

- In 1920, the party changed its name to the National Socialist German Workers Party (NSDAP) to reflect its new ideology. The term "National Socialist" indicated the party's commitment to socialism, but with a strong emphasis on nationalism and racial purity.

- The party gained support by capitalizing on the economic and political instability in post-World War I Germany. It appealed to those who were disillusioned with the Treaty of Versailles and the Weimar Republic, promising to restore German pride and prosperity.

- The NSDAP's rise to power was aided by Hitler's charisma and oratory skills. He was able to rally large crowds and gain the support of various interest groups, including workers, farmers, and the middle class.

- The party's paramilitary organization, the Sturmabteilung (SA), also played a crucial role in intimidating political opponents and enforcing party discipline.

- In 1933, the NSDAP emerged as the largest party in the German parliament (Reichstag) after the general elections. Hitler was appointed as the Chancellor of Germany, and the party began implementing its radical agenda, including the suppression of political opposition, the persecution of Jews and other minorities, and the rearmament of Germany.

- Under Hitler's leadership, the Nazi Party transformed Germany into a totalitarian state, leading to the outbreak of World War II and the perpetration of the Holocaust.

In conclusion, the party that came to be known as the Nazi Party was the National Socialist German Workers Party (NSDAP), which emerged in Germany in the 1920s and was led by Adolf Hitler.
