Nazi seizure of power
The Nazi regime abolished the symbols of the Weimar Republic, including the black, red, and gold tricolour flag—and adopted reworked symbolism. The previous imperial black, white, and red tricolour was restored as one of Germany's two official flags; the second was the swastika flag of the Nazi Party, which became the sole national flag in September 1935. The party anthem "Horst-Wessel-Lied" ("Horst Wessel Song") became a second national anthem.
