Answer:
The Nazi party became the largest party by organized the Bamberg Conference. Hitler wanted to reunify the party, and set out a plan for the next few years. Whilst some small differences remained, Hitler was largely successful in reuniting the socialist and nationalist sides of the party.
In the same year, Hitler restructured the Nazi Party to make it more efficient.
Firstly, the Nazi Party adopted a new framework, which divided Germany into regions called Gaue. Each Gaue had its own leader, a Gauleiter. Each Gaue was then divided into subsections, called Kreise. Each Kreise then had its own leader, called a Kreisleiter. Each Kreise was then divided into even smaller sections, each with its own leader, and so on. Each of these sections were responsible to the section above them, with Hitler at the very top of the party with ultimate authority.
The Nazis also established new groups for different professions, from children, to doctors, to lawyers. These aimed to infiltrate already existing social structures, and help the party gain more members and supporters.
These political changes changed the Nazi Party from a paramilitary organization focused on overthrowing the republic by force, to one focused on gaining power through elections and popular support.
Explanation:
Long story short the Nazi party got to power so quickly by many reasons. Hitler had a lot of supporters, ended up brainwashing people basically, and not only were grown adults part of the Nazi Party, Hitler created something called "Nazi Youth" which was basically the teaching and brainwashing of young kids/teenagers on how to fight.
