Final answer:
The Nazi Party borrowed the swastika from ancient Indian and Central Asian cultures, where it symbolized good fortune, long before Adolf Hitler adopted it for the Nazis, linking it to a mythical 'Aryan' race.
Step-by-step explanation:
The Nazi Party borrowed the swastika symbol from ancient civilizations, where it was originally a symbol of good fortune. The swastika was used for millennia in various cultures, particularly in India and Central Asia. After the war, Adolf Hitler joined the German Workers Party and, finding like-minded individuals, quickly rose to become the leader of what was renamed the National Socialist German Workers Party, or Nazi Party for short. A skilled orator with radical ideologies, Hitler adopted the swastika as the party's emblem, associating it with the fabricated notion of an ancient "Aryan" race. The benevolent meaning of the swastika was lost as it became synonymous with the horrific actions and ideology of the Nazi era.
The use of the swastika by the Nazis was a part of their larger propaganda effort to reconstruct German culture and identity based on their vision of a racialized, militaristic, and "purified" German nation.
