The flag of Nazi Germany, officially called the Reich and National Flag (German: Reichs- und Nationalflagge [1]), featured a red background with a black swastika on a white disk.

The 20th-century German Nazi Party made extensive use of graphic symbols, especially the swastika, notably in the form of the swastika flag, which became the co-national flag of Nazi Germany in 1933, and the sole national flag in 1935. A very similar flag had represented the Party beginning in 1920.

After World War II, black-white-red was still used by some conservative groups or by groups of the far right, as it is not forbidden, unlike specific Nazi symbols such as the aforementioned swastika. Black-red-gold is the official flag of the Federal Republic of Germany.

When Germany was unified at the end of the 19th century, the national flag had stripes of black-white-red. After the defeat of the Second Reich in World War I, that flag was replaced by the black-red-yellow under the Weimar Republic. Many Germans, however, rallied around other flags they felt better represented the true German spirit.
